[WIP] fix: watch mode using chokidar v4 (#5355)

[Arnesfield]

Glob paths are no longer supported by chokidar starting at v4.

This update works around this by resolving watchFiles and watchIgnore to valid paths and creating a list of matchers to determine if the files should be allowed or ignored through the chokidar ignored match function.

This commit reverts changes from 8af0f1a so that the watched file changes are not fixed to the current directory.

Additional note: when a watchFile path is removed while chokidar is watching it, recreating the watchFile path does not trigger events from chokidar to rerun the tests.

Might need to rethink this a bit. Currently, running into some issues:

• The test reruns test when file matching --watch-files is added doesn't pass
• The watchFiles for this test are: **/*.xyz
• From what I understand, the actual test result looks like it has an additional rerun (3 instead of the expected 2) which I think is probably due to the directory being created (lib/ then lib/file.xyz)
• But ignoring the directory in chokidar means its contents are also ignored
• Need a way to not ignore a directory (lib) but also only allow contents to trigger a rerun (*.xyz)
