There are both mechanical and logical changes in this patch.
The mechanical changes involve moving some files into the mozbuild
package.
The logical changes include move writing of mozinfo.json into
config.status (from configure.in). There were some variable assignments
being performed in configure.in. These variables were read from
writemozinfo.py. However, these variables don't appear to be necessary!
Now that mozinfo has full access to the underlying config.status data
structure, it can now access these variables directly. I verified that
every variable being assigned in configure.in had a corresponding
AC_SUBST earlier in the file.
The only variable that's a bit weird is the TOPSRCDIR and MOZCONFIG
environment variables. mozinfo continues to look in the environment for
MOZCONFIG. However TOPSRCDIR is now coming from config.status.
As part of moving the code, I also modernized the test file, cleaned up
some style, and removed some unused imports.

rename : config/tests/unit-writemozinfo.py => python/mozbuild/mozbuild/test/test_mozinfo.py
A new build tier is introduced: precompile. The intention is to replace
the export subtier with something better and nonrecursive. IPDL and
WebIDL code generation have been moved into this new tier and are
performed concurrently. This appears to reduce build times due to fewer
"single threaded" build actions.
The subtier tracking UI has been updated to reflect operations that can
occur in parallel. As subtiers are started, they turn yellow. They can
then complete in any order.
Nonrecursive targets have been added to preserve the IPDL and WebIDL
build targets such that developers can type |make| from leaf directories
like they have always done.
