Add Linux/GCC compatibility

[jonpas]

Not tested on MSVC at all.

• [x] intrin.hpp header is MSVC-specific, can use x86intrin.hpp with GCC.
• [x] zstd is 4 years old and using deprecated CMake stuff.
• [x] Absolute include paths (src\...).
• [ ] Code is using __debugbreak() which is MSVC-specific.
• [ ] lzokay is not GCC 12 or Clang 13 compatible (std::being/end). https://github.com/jackoalan/lzokay/pull/5

Code is using__debugbreak() which is MSVC-specific.

What about using https://github.com/nemequ/portable-snippets/blob/master/debug-trap/debug-trap.h mentioned in https://stackoverflow.com/questions/173618/is-there-a-portable-equivalent-to-debugbreak-debugbreak ?

Or cherry-picking

__asm__ volatile("int $0x03");

from it?

I use these in most of my newer projects. Could replace the debugbreaks by these helper methods

https://github.com/intercept/interceptAR/blob/master/src/common/util.hpp#L170-L207

lz compression is optional, it can be turned off, though that would make all linux compiled scripts be less size efficient

Macro-ize and use other method for GCC.

lzokay probably isn't the only library doing this, could be replaced with something else.

Approve workflows so we can see if Windows builds are being broken with this.
