This narrows the scope of the CRC to try to get better behavior around
mutex lock releasing on crash. Closes#5042.
This breaks apart `ProcessTestFileAndRun` because we need to process the
test file for `SET-CAPTURE-CONSOLE-OUTPUT`. The test file processing
should more reliably not crash than the core `Run` logic though, so
should be reasonably safe to put outside the CRC.
Also support --threads=1 for disabling threading. This is the flipside
for me of reducing how much is in the CRC: make it easier to run on a
single thread if the CRC gets in the way of debugging. This also means a
typical copy-paste execution of a single test will be single-threaded.

I'm refactoring logic to try to make these files more manageable,
particularly as I'm looking at ways to use more threads. I'm renaming
FileTestBase::TestContext to TestFile and FileTestBase::TestFile to
TestFile::Split to try to be more consistent in how we talk about test
files and file splits in general. This change is not expected to change
any behavior, it's just refactoring.
This PR has two commits:
- Copying files for viewing deltas in GH
- Moving logic
The delta of the two commits is the main PR. The second commit can be
viewed on its own to see the delta versus file_test_base.* files where
the logic currently rests (there's still a reordering in run_test.cpp as
part of making one function static).
