Set up 32-bit Linux CI action and MinGW action

[sharadhr]

Relates to #2583. This would be good to test cross-compiling scenarios. It will also catch issues such as #2468.

Hey, Opened #2585 for the 32-bit Linux CI part.

Added the Ubuntu 24.04 x86 matrix entry using gcc/g++ multilib with -m32.

I did not covered the MinGW part because its a work on its own 😅

[danyalahmed1995]

Alright Linux GCC/multilib is done, now I'm gonna do the minGW and clang runner ci . @sharadhr & @M2-TE two separate PR for both of them would be better right? Or you guys prefer one.

I would also prefer to have them separated. Especially if either one causes problems.
Thanks for tackling this work!
