mingw: re-enable endbr opcode, add workaround for clang `cet.h` issue
- https://github.com/libressl/openbsd/pull/149 fixes to crash
on startup issue, thus nuking all endbr opcodes is no longer
necessary. This effectively enables CET in ASM code for
MinGW x86_64 builds.
- llvm `cet.h` (as of v18) assigns `endbr32` instead of `endbr64`
to `_CET_ENDBR` macro for MinGW x86_64 targets.
https://github.com/llvm/llvm-project/blob/llvmorg-18.1.1/clang/lib/Headers/cet.h#L15-L35
Work this around by mapping `endbr32` to `endbr64`.
Prerequisite: https://github.com/libressl/openbsd/pull/149
Fixes: https://github.com/libressl/portable/issues/1015
