  Reland "Vulkan: Implement debug markers"
  
  This reverts commit 0c01e36783b20a0177c653490cb4f8ea4a896075.
  
  Reason for revert: Its dependency that was reverted has now relanded:
  
      https://chromium-review.googlesource.com/c/angle/angle/+/1489153
  
  Original change's description:
  > Revert "Vulkan: Implement debug markers"
  >
  > This reverts commit 983e446921946734fe47217c345a8fe2f079319d.
  >
  > Reason for revert: Depends on a CL that's reverted: https://chromium-review.googlesource.com/c/angle/angle/+/1470605
  >
  > Original change's description:
  > > Vulkan: Implement debug markers
  > >
  > > Covers both GL_KHR_debug and GL_EXT_debug_marker.
  > >
  > > Debug markers are used to specify events or hierarchically categorize a
  > > set of commands within the command buffer.  When debugging, this allows
  > > for quicker navigation to the draw calls of interest, and otherwise
  > > provides context to debug output.
