gallium: Add PIPE_CAP_FRAMEBUFFER_NO_ATTACHMENT
Add PIPE_CAP to determine if the GL extension
'GL_ARB_framebuffer_no_attachments' shall be
supported.
The driver is required to support 'PIPE_FORMAT_NONE'
via its 'is_format_supported()' callback in order
to determine the MSAA modes the hardware supports so
that values requested from the application using
'GL_ARB_framebuffer_no_attachments' may be quantized
to what the hardware expects.
V.2:
Fix doc for a more detailed description of the PIPE_CAP
and the corresponding GL constant.
V.3:
Renamed and repurposed once again.
V.4:
Remove CAP from cap_mapping array.
