  Merge ESSL pre-processsor token errors
  
  In both the ESSL 1.00 & 3.00 specifications having an extension directive
  after a pre-processor token is an error. Merging those two enum cases to
  be a single case. WebGL is handled as a separate warning case for any
  shader version before 3.00.
  
  Also this change now correctly marks 1.00 shaders that break this rule
  to be invalid so the ExtensionAfterNonPreProcessorTokenESSL1 test no
  longer expects handleExtension() to be called.
