Pre-compile binaries for Windows

[vinistock]

Pre-compile Rubydex binaries for Windows. In addition to making the gem install much faster, pre-compilation also eliminates the need for users to have cargo in their machines.

The changes are:

• Including windows-latest in the matrix
• Bumping gem installation timeout (5 minutes is sometimes not enough for Windows)
• Ignoring incompatible pointer types warnings. On Windows, we get warnings regarding passing void pointers when registering methods with rb_define_method that would require casting everything

Successful dry-run
