[cleanup] Unify test naming

Unifying all test files to have a common suffix. This make using
tool simpler as we have 1 way to define files.
Examples are:
Custom scripts we write, explain to AI what files are test files,
Lint rules, IDE search / ignore.

Part 1 - only migrate Extensions as they take the longest to build,
test and land.
