Summary:
D91738264 split the Flow and Hack tests into smaller targets to avoid CI timeout/OOM issues, but the OSS CI was subsequently disabled in D92338196.

This diff re-enables the Flow tests in OSS CI by:

  1. Removing -f-flow-tests from the disabled test flags in both CI workflows
  2. Splitting the glass-regression-flow test suite into 7 smaller suites using an m4 macro
  3. Adding a test-flow-glass Makefile target that iterates over the split tests

The split test suites mirror the internal Buck targets:

  • flow-describe, flow-document, flow-references, flow-resolve
  • flow-search-basic, flow-search-prefix, flow-search-prefix-empty

Hey @phlalx, I wasn't aware that this test was slow, has it got slower recently? Could there be a regression, or something dumb going on to make it slow?
