  Revert "Vulkan: Make available GLInternalFormatToGbmFourCCFormat"
  
  This reverts commit 402e7f7a634b1170d0feae52a44168731a7489f9.
  
  Reason for revert: Chromium android-binary-size build failed.
  
  Original change's description:
  > Vulkan: Make available GLInternalFormatToGbmFourCCFormat
  >
  > GLInternalFormatToGbmFourCCFormat() is not available on Linux
  > because of the guard with the wrong definition, ANGLE_USES_GBM.
  > This also fixes build errors that were occurred after enabling.
  >
  > Bug: angleproject:7829
