R11G11B10F support

- Moved the R11G11B10F conversion code from the Blitter to
  ShaderCore
- Used the conversion code in PixelRoutine where appropriate
  to make the R11G11B10F work as a renderable format
- Added the VK_FORMAT_FEATURE_COLOR_ATTACHMENT_BIT and
  VK_FORMAT_FEATURE_BLIT_DST_BIT to the
  VK_FORMAT_B10G11R11_UFLOAT_PACK32 format

This allows ANGLE to expose the GL_EXT_color_buffer_float
(and GL_EXT_color_buffer_half_float, which depends on
GL_EXT_color_buffer_float in ANGLE, due a driver issue).
