Rémi Verschelde e91a267a7c Buildsystem: Improve detect.py readability and fix issues
Tried to organize the configure(env) calls in sections, using the same order
for all platforms whenever possible.

Apart from cosmetic changes, the following issues were fixed:
- Android: cleanup linkage, remove GLESv1_CM and GLESv2
- iPhone: Remove obsolete "ios_gles22_override" option
- OSX:
  * Fix bits detection (default to 64) and remove obsolete "force_64_bits" option
    (closes #9449)
  * Make "fat" bits argument explicit
- Server: sync with X11
- Windows: clean up old DirectX 9 stuff
- X11:
  * Do not require system OpenSSL for building (closes #9443)
  * Fix typo'ed use_leak_sanitizer option
  * Fix .llvm suffix overriding custom extra_suffix
