Upgrade rake-compiler for Ruby 3.2 prebuilt binaries

[johnnyshields]

Please release binaries which support Ruby 3.2 after merging this. It seems in particular x64-mingw-ucrt is not being supported for Ruby 3.2 (it works on Ruby 3.1)

I already tried the new RCD version with ffi, but it fails to build libffi for ruby-3.2 on x86-mingw32 like so:

I didn't investigate it deeper though.

The offending line in libffi is here: https://github.com/libffi/libffi/blob/7611bb4cfe90884b55ad225e0166136a1d2cf22b/src/x86/win64.S#L48

[johnnyshields]

Thanks! Should a ticket be filed with libffi?

[larskanis]

Probably not, given that libffi compiles fine on ruby-3.1 in RCD and ruby-3.2 on native RubyInstaller on Windows.
