  -----------
  [libc][NFC] Move float macro into its own header / add target os detection (#73311)

Floating point properties are a combination of target OS, target
architecture and compiler support.
 - Adding target OS detection,
 - Moving floating point type detection to its own file.

This is in preparation of adding support for `_Float16` which requires
testing compiler **version** and target architecture.
