Change optimization level for Win32 builds
This fixes #20136.
Building on Windows 11 with the Strawberry 5.32.1 (gcc 8.3.0) toolchain,
multiple errors in the tests are seen. Worse, building on Windows 10
no test errors crop up, but the resulting perl will still crash and die
when run the tests manually on Windows 11.
Changing the optimization level to -Os as found in #20024, the build now
and tests now succeed.
