gallium/docs: clarify definition of PIPE_CAP_USER_CONSTANT_BUFFERS, etc
The cap means _can_ accept user-space constant buffers; it doesn't
mean _only_ accepts user-space constant buffers.
v2: also update the PIPE_CAP_USER_VERTEX_BUFFERS and
PIPE_CAP_USER_INDEX_BUFFERS descriptions as well. Per Jose.
