We add to `GARBAGE_DIRS` in the toplevel `Makefile.in` because all of
our Rust libraries share a single `CARGO_TARGET_DIR`, located in
topobjdir.
We add to `GARBAGE_DIRS` for Rust programs because Rust programs
currently do not share compilation artifacts with Rust libraries (as our
libraries are built with `panic=abort` and our programs are not, sharing
compilation artifacts between the two is a non-starter).

Summary:
- ICU no longer supports removing resource files manually, instead the new data
filter builder needs to be used.
- This includes test data, which also must be preserved in ICU 64.
- umutex.h contains an implicit call to `new` in ICU64 which needs to be allowed
in check_vanilla_allocations.py.
- Drive-by: Make ICU with multiple jobs for faster rebuilds.

The current setup uses different ways for different platforms, with
different workarounds, even using extra configuration items for Windows.
Now that there can't be a difference between the host per the build
system and the host per rust, we can get rid of those configuration
items, and use a more common infrastructure.
We cannot, however, avoid using wrapper scripts, because per-target rust
link-arg flags don't work up great.
The downside is that multiplies the number of wrappers, as we now have
to have a different one for host and target, and then we have .bat files
and shell scripts for, respectively, Windows hosts, and other hosts.

This is being changed in Firefox's build config rather than NSPR's
to avoid possibly introducing regressions into other NSPR users due
to bugs in MacOS's poll, such as the POLLPRI issue addressed in the
previous patch. (There is also a known bug when calling poll() with
zero descriptors, but PR_Poll already has code to call PR_Sleep instead
in that case.)

On one-go MOZ_PGO builds, it's generally not wanted to do LTO during the
profile-generate phase. And the build system doesn't really support
different build options between both phases in this case, so we relied
on MOZ_PROFILE_GENERATE to disable the LTO flags.
However, in standalone profile-generate builds, if --enable-lto is
passed explicitly, the build should respect that choice.
So instead of checking MOZ_PROFILE_GENERATE to disable the LTO flags,
we disable them when MOZ_LTO is not set, and we force it to be disabled
during the profile-generate phase of one-go MOZ_PGO builds.

This patch adds detection for when icecream is in use to build telemetry.
icecream is commonly enabled in two ways: by either setting CC/CXX to point
to icecream's cc/c++ symlinks, or by setting adding
mk_add_options 'export CCACHE_PREFIX=icecc' to a mozconfig when also using
ccache. For the former, this patch adds a simple configure check to see
if CXX is a symlink to a file named 'icecc'. For the latter this patch adds
CCACHE_PREFIX as a configure subst to capture the value.
We don't currently have a facility for writing telemetry tests that depend on
configure values. Local manual testing shows that it does work as expected.

Consequently, this removes:
- MOZ_LIBPRIO, which is now always enabled.
- non_msvc_compiler, which is now always true.
- The cl.py wrapper, since it's not used anymore.
- CL_INCLUDES_PREFIX, which was only used for the cl.py wrapper.
- NONASCII, which was only there to ensure CL_INCLUDES_PREFIX still
worked in non-ASCII cases.
This however keeps a large part of detecting and configuring for MSVC,
because we still do need it for at least headers, libraries, and midl.

While this isn't related to the bug, since we're going to touch the
cargo compiler flags, we might as well do this too.
It wasn't previously reliable to pass those flags down because what
cargo uses as target for build scripts and procedural macros is
determined by the rust host, which was not necessarily the same as the
build system host. But as of bug 1523143, they are always the same.

Now that Make invokes cargo without going through an msys shell,
environment variables are going to be preserved properly, and we can now
"safely" pass the compiler-related variables down to cargo on Windows.
This makes rust target builds use the expected compiler and flags,
instead of the cc-rs crate guessing, picking cl.exe, and using the wrong
one, with the build later failing when linking it all together because
one of the objects is not for the right target.
Interestingly, the lmdb code is today built for the wrong target on
aarch64, but somehow, it doesn't break the build on automation,
presumably because the lmdb code is actually dead code, and the linker
eliminates the object as unused, masking the problem.

Double quotes on a command line forces Make to use a msys shell when

The `env` program, on windows, comes from msys, so invoking `env cargo`
guarantees an msys roundtrip, which usually breaks environment variable
in interesting ways.
This moves most of the environment variables we set with `env` (the
easiest ones) to exporting the same values from make itself.

Because we're going to change how cargo recipes are called to export
environment variables rather than by wrapping the call with `env`, to
avoid msys roundtrips, it's better to avoid the complexity when not
building rust, and including a separate file only when required helps
with that. It is also possible to wrap the entire rust section of
rules.mk in the same condition we use for the include, but using a
separate file also makes things clearer.

We default to -Zi for Windows debug flags, which is for generating debug info
into a PDB file, but clang-cl doesn't actually implement that so -Zi is
an alias for -Z7 in clang-cl:
http://clang.llvm.org/docs/UsersManual.html#id9
sccache has special handling for -Zi because multiple compiles writing
to the same PDB file is not cacheable, so we've always overridden -Zi with -Z7
in CI when using sccache.
Given that everyone should be using clang-cl nowadays and MSVC will no longer
be supported soon, this patch changes the default and removes some PDB
file name flag setting from rules.mk, as well as the no-longer-necessary
overrides from mozconfig.cache.
