`ProcessPoolExecutor` will naturally default to the number of CPUs on
the machine and will also handle edge cases on Windows.

Use finer granularity for some reftest/mochitest SCHEDULES.exclusive entries,
so that reftest-plain does not run when only crashtests are modified, and
vice versa; similarly, break up mochitest into mochitest/browser-chrome/chrome/
a11y. Use schedules-component instead of category.

In the process, fixed a few bugs:
- the template eg `{file_adds % "\n{file}"}` produced a leading blank line,
which led to everything being linted.
- 'd' was replaced with 'r' in diff_filters, but the replacement was discarded.
- as a result of the above, `hg status -d` was being used ("show only deleted (but tracked) files") and now it is `hg status -r` ("show only removed files"). I *think* this is what was intended?

Adds --config-paths parameter to mach mozlint where test configuration
files (.yml) can be located. The default path "tools/lint" is set automatically
and additional paths have preference over the default.
This allows Thunderbird to run mozlint-based tests in Taskcluster with a
different configuration.

While we validate user specified paths early and only consider the 'AM' (added
+ modified) diff filter from versioncontrol, it's still possible to get
non-existent files when using --outgoing. This situation can happen when you
have a commit series that first modifies a file in an earlier commit, and then
moves/deletes it in a later commit.
To get around this, just silently filter out any file paths that don't exist.

Dictionary iteration under Python 3 is in an inherently unpredictable order, and while we try to keep DEFINES ordered through the use of OrderedDicts, if at any point we populate DEFINES directly or indirectly while iterating through the contents of a non-ordered dictionary, the order of the DEFINES (and therefore the contents of the output Makefile) will be nondeterministic as well. This patch makes a number of changes to ensure that we only ever populate DEFINES in a deterministic fashion. (Note that in Python 3.7 and later, the built-in dict class actually has deterministic ordering, so these changes are technically only necessary until our minimum Python version becomes 3.7.)

LLVM's new pass manager has been in the works for several years and has better optimization (sometimes much better) than the legacy pass manager. I think it's in good enough shape for us to try at this point.
While we only really need the new pass manager for shippable builds, as a general principle I'd like to use it as much as possible, to help catch bugs for upstream. Therefore this patch enables the new pass manager by default for all clang builds, with the only exceptions being compilers older than version 9, and xcode clang where we can't trust the version number. There isn't a specific problem with older versions; I just don't want to sign up for the support cost of debugging people's local builds that may be fixed already.
I don't expect it to be necessary, but just in case, an opt-out is available via `ac_add_options --disable-new-pass-manager`.
