Having a full VPATH for the srcdir sometimes causes make to grab the
wrong prerequisite for a rule, in particular if we have a file in the
srcdir and also generate a file of the same name in the objdir. We don't
really need VPATH anymore though, since most of the information comes
from mozbuild, where we can explicitly list the path to the srcdir or
objdir as necessary.

Make depend files related to object files are only really useful when
the corresponding build targets are being processed. OTOH, when they are
included too broadly, when the build recurses in the same directory for
different targets (e.g. target-objects, target, host-objects and/or
host), it is possible for one of them to start creating depend files
that the others would end up reading, and those reads might be
incomplete, possibly leading to build failures because Make think it's
malformed.
So, we only include the object files's depend files in when Make is
explicitly treating a target that will build objects.

Make the target and host targets depend on those, and flatten the
dependencies.
That is, instead of chains like:
browser/app/target: mozglue/build/target
mozglue/build/target: memory/build/target
we now have:
browser/app/target: browser/app/target-objects \
mozglue/build/target-objects \
memory/build/target-objects
Which means Make can feel free to build the object files in browser/app
before building other dependencies.

When a directory, like toolkit/library, builds both a static and a
shared library, and another, like toolkit/library/gtest, depends on the
static part, it currently needs to wait for the shared library to be
finished building, preventing both libraries being built in parallel.
By separating shared libraries to a different target, we allow more
parallelism to the build.

The condition that enabled ELOG to do something has been broken since
bug 279212 landed two years ago, because MAKEFLAGS doesn't contain the
dash for flags, so looking for "-s" never did anything.
Bug 1560527 changed the condition to !BUILD_VERBOSE_LOG, which as of the
previous commit, does work. This would restore the old behavior, at the
expense of build time, since it involves wrapping in a shell script,
which is not necessarily desirable (and hasn't been done for two years
now)

Windows 1-tier PGO builds only partially clobber between the
profile-generate and profile-use stages, so that exports/installed files
don't have to be reprocessed. Unfortunately we can't skip the install
manifests in 3-tier PGO because the profile-generate build happens on a
different machine, so we have to differentiate between 1-tier and 3-tier
PGO builds. A new variable, MOZ_1TIER_PGO, is used for this purpose.
Eventually this logic can be cleaned up in bug 1557788 once all PGO
builds use the 3-tier model.

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.

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.

Because MSVC compilers only support one architecture, we need to search
"cl" in different toolchain search paths for each of the host and
target, especially when they are different.
Likewise for the library paths for the linker. Ideally we'd pass
-LIBPATH both for host and target, but that has implications for rust
that I don't want to have to figure just now.

BUILD_TOOLS was only ever used for things that another variable provides
equally well. Removing BUILD_TOOLS means that we can remove win_srcdir
and WIN_TOP_SRC as well.
All but one of the current uses of DEFFILE use `SRCDIR + '/file.def'` to
get a srcdir-relative path anyway, and the other one wants an
objdir-relative path, so using Path makes everything clearer.
This makes it more straightforward to translate the paths for the WSL
