GHA/windows: replace GfW with MSYS2 runtime downgrade
We recently switched to a known good version of Git for Windows to avoid
the MSYS2/Cygwin runtime performance regression.

MSYS2 is closer to the source of the MSYS2/Cygwin projects. Its known
good version is newer. Installing the downgrade is faster and safer. It
also allows to restore the scripts to their original iteration, making
the workaround easier to drop once the perf issue is fixed upstream.

Therefore, switch back to using MSYS2, and install the runtime downgrade
before running curl tests.

Also disable `pacman`'s `CheckSpace` for best performance.

Jeremy identified to the root cause of the perf regression in this
Cygwin commit (from 2024-09-17):
