To adopt PR #1264 approach of using Readline replacement for MinGW build (Low Priority)

[mcuee]

PR #1264 has been merged and it performs much better than using GNU Readline under Windows. It is good to adopt the same approach for MinGW.

I add this as part of the AVRDUDE 7.2 milestone. But you can remove this if you feel that this is of lower priority. Thanks.

PR #1513 (Add GNU Readline to mingw github action) brings in undesired dependency of libwinpthread-1.dll to the mingw32/mingw64 binaries. I have to revert the PR.

It is very strange that there is no such side effect under my own MSYS2 ming64 build.

Anyway, I think it is better to use the approach used by @mariusgreuel for MSVC to the MinGW build as well since GNU Readline is not that good under Windows.
