[presubmit] Add include guard check

This check verifies that all .h files in the src/ directory have an
include guard of the form

 #ifndef V8_PATH_TO_FILE_H_
 #define V8_PATH_TO_FILE_H_
 // ...
 #endif  // V8_PATH_TO_FILE_H_

The check can be skipped with a magic comment:

 // PRESUBMIT_INTENTIONALLY_MISSING_INCLUDE_GUARD
