Merge utility/support changes from "wilds" to "master"

Ref T13395. Merge a lot of stuff which doesn't break existing workflows:

  • Merge a UTF8 fix for "cmd.exe" on Windows.
  • Merge minor changes to JSON linters.
  • Merge some shell completion stuff.
  • Merge some "arc anoid" fixes.
  • Merge various Windows improvements to unit tests which interact with processes / the filesystem.
  • Merge some other Windows path fixes.
  • Merge a UTF8 character class fix.
  • Merge script initialization.
  • Merge unit test support scripts.
  • Merge some initialization code.
  • Merge Windows stdout/stderr-as-files code.
  • Merge a bunch of code for making exec tests work on Windows.
  • Merge more Windows unit test fixes.
  • Merge "continue on failure" mode when loading symbols.
  • Merge "GPC" order CLI fixes.

Test Plan: Ran arc unit --everything; created this change. There's likely some less-than-perfect code here.
