dri: Change __DriverApiRec::CreateContext to take a struct for attribs 

Previously the CreateContext method of __DriverApiRec took a set of
arguments to describe the attribute values from the window system API's
CreateContextAttribs function. As more attributes get added this could
quickly get unworkable and every new attribute needs a modification for
every driver.

To fix that, pass the attribute values in a struct instead.  The struct
has a bitmask to specify which members are used. The first three members
(two for the GL version and one for the flags) are always set. If the
bit is not set in the attribute mask then it can be assumed the
attribute has the default value. Drivers will error if unknown bits in
the mask are set.
