Currently mozconfig.cache overrides a few build options for sccache. This
patch moves them into toolchain.configure so that the build system will
set them properly when sccache is in use. Additionally, {CC,CXX}_WRAPPER
are set in config.mk, so just avoid setting them when sccache is in use.

We've been using -Z7 to make MSVC emit CodeView debug info directly in
the object files instead of in PDB files because sccache can't cache
PDB files if the same one is written to by multiple compiles, which
was previously happening in our build system, and was hard to override
in the NSS build. Now that those are fixed this should work fine.
This adds a bit to the compile rule to remove the PDB file before
compilation, since sccache won't cache a compilation if the PDB file
it is supposed to generate already exists (for the aforementioned reason).

This patch does a few things:
1) Change all the in-tree tooltool manifests to contain sccache2 instead of the existing Python sccache
2) Change mozconfig.cache to point at sccache.
3) Lightly tweak the --with-cccache configure option to support sccache, and detect whether we're using ccache or sccache and set an option appropriately.
4) Add a MOZ_SCCACHE_VERBOSE_STATS option, and add a target in the top-level Makefile to make sccache spit out its stats at the end of the build. This is useful to see the cache hits/errors until we get something better.
5) Add MOZ_USING_SCCACHE to the build telemetry. Not that I think it will be immediately useful, but for future use.

This should have been done when autoland came into existence.

fx-team is read only. We shouldn't be performing any more builds. The
configuration can be removed.

Sccache was enabled mechanically by the switch to EC2 Windows instances, while
it is not intended to be used on PGO builds.
This happened because the fix for bug 1181040 disabled sccache for PGO builds
where MOZ_PGO is set through mozconfig (in which case MOZ_PGO_IS_SET is set)
*while* ignoring the case where MOZ_PGO is set through the environment (in
which case MOZ_PGO_IS_SET is, unconveniently, *not* set). The latter is what
Windows PGO builds do.
The way UPLOAD_EXTRA_FILES is currently exported makes the files added
to the list added in each directory that is being traversed recursively
because of the += in .mozconfig.mk, combined with "export".
The easy way out is to remove the export altogether, but being unsure of
the side effects of putting all non exported mk_add_options variables
in .mozconfig.mk, limit this to UPLOAD_EXTRA_FILES.
