Improve runtime CPU feature detection

- Make wimlib_global_init() do the CPU feature detection, so that it
  doesn't have to be done on-demand later.

- Add support for detecting the x86 SHA extensions.

- Add support for detecting ARMv8 SHA1 instructions on Linux, Windows,
  and macOS.  (64-bit only for now.)

- Allow disabling features via an environment variable for testing.

- Remove some unused functionality.
