Support API versioning in platform-specific headers (see #3836)

- Exclude platform-specific includes (anything in < >) from the
  clang preprocessor by using `!defined(GENERATING_CEF_API_HASH)`
  in CEF header files.
- Define "target platforms" by passing platform- and architecture-
  specific ifdefs to the clang preprocessor. Grep for `defined(OS_`
  to identify headers that require target platform processing, and
  then process for each target as the platform-specific API hash
  contribution.
- Delete the univeral hash which is no longer a useful concept.
