multimedia/{lib}x264: Update to 0.144.2533 and major refactor

- Update to 0.144.2533 (from upstream stable branch) [1]
- Switch x264 and libx264 ports to master/slave ports respectively
- Bump PORTREVISION for dependent ports as the shared library version
  has changed.

multimedia/x264:

- Clean up and update "updating instructions" in Makefile header
- Tweak COMMENT
- Only LIB_DEPENDS on libx264 and add PLIST_FILES if this isn't the
  libx264 port.
- Allow COMMENT, USES, OPTIONS_*, CONFIGURE_ARGS to be overriden in
  libx264 port.
- Place common configure arguments in a CONFIGURE_COMMON_ARGS variable
  to make overriding values without duplication easier.
- Use --prefix configure argument over post-patch replacements
- Enable stripping of binaries and libraries if DEBUG is off. Remove
  post-install target STRIP_CMD accordingly.

- Delete patch-Makefile in favour of patching WRKSRC/configure to
  identify amd64, arm64 and mipsn32. powerpc and powerpc64 are now
  covered upstream without needing patches.

- Patch out a bogus compiler argument check (cc_check) that results
  in -Wno-maybe-uninitialized being added to CFLAGS causing causes
  warnings when clang is cc. The cc_check function checks for basename
  $CC to identify compiler type (icl, clang, gcc, etc).

multimedia/libx264:

- Remove all Makefile entries that are duplicated or common and found
  in the master port (x264).
- Set lib as the PKGNAMEPREFIX
- Tweak COMMENT
- Delete upstreamed ARM patches [1]
- Delete all but one patch, as they duplicate those in x264.
- Dont remove pkgconfig/libdata directory
