feat(ci): make recording workflow simpler, more parameterizable (#3169)

# What does this PR do?

Recording tests has become a nightmare. This is the first part of making
that process simpler by making it _less_ automatic. I tried to be too
clever earlier.

It simplifies the record-integration-tests workflow to use workflow
dispatch inputs instead of PR labels. No more opaque stuff. Just go to
the GitHub UI and run the workflow with inputs. I will soon add a helper
script for this also.

Other things to aid re-running just the small set of things you need to
re-record:
- Replaces the `test-types` JSON array parameter with a more intuitive
`test-subdirs` comma-separated list. The whole JSON array crap was for
matrix.
- Adds a new `test-pattern` parameter to allow filtering tests using
pytest's `-k` option


## Test Plan

Note that this PR is in a fork not the source repository.

- Replay tests on this PR are green
- Manually
[ran](1699856292)
the replay workflow with a test-subdir and test-pattern filter, worked
- Manually
[ran](4819508034)
the **record** workflow with a simple pattern, it has worked and updated
_this_ PR.
