From: Gert Wollny <gert.wol...@collabora.com>
Add a new cap that indicates whether the drivers supports
enabling/disabling the conversion from linear space to sRGB
for a framebuffer attachment. In Driver terms that this CAP indicates
whether the driver can switch between a linear and and a sRGB surface
format for draw destinations without changing the surface itself.
v2: rename CAP to DEST_SURFACE_SRGB_CONTROL to reflect its
purpouse better (pointed out by Ilia Mirkin)
