CI: merge mingw test CI jobs

[Kobzol]

Same as #112633, but for mingw. From the logs it looks like the runner spends 40 minutes compiling rustc, and then 10/20 minutes running tests. It seems wasteful to split that into two jobs.

I applied jyn's suggestion to test both entrypoints (x and bootstrap.py).

Converting to draft until #112668 is resolved.

[Kobzol]

Performed the same change as in #112668, testing if it works on PR.

[Kobzol]

Good, tests now pass.

This must be noise, Linux wasn't affected.
