Completely dismantle Actions-based tests except for combinatorics

[workingjubilee]

There are sets of tests that we have that should just be entered by a single command, like the tests for the individual "example extensions". They make fixing problems with them extremely slow because like fuck is anyone going to set up the actions runner on their desktop just to be able to run local testing, and thus everyone who contributes to pgrx, including myself, is averse to refactoring them.

related:

• Can we reorganize pgrx-examples into a more "normal" examples directory? #1554
• Extract more CI tasks to shell scripts/Rust tools #1565
• Test that pgrx can build after publishing #1796

act exists but word on the block is it kinda sucks. I'm guessing it has the problem of not actually being the same as the runner. It doesn't even seem to fully support the GHA yamlscript.

Have you considered the way bevy went? It allows to run the exactly same thing both in the CI and locally: https://github.com/bevyengine/bevy/tree/release-0.14.2/tools/ci.

@YohDeadfall That's basically my intention, yes.
