gallium: separate out floating-point CAPs into its own enum
The motivation behind this is to add some self-documentation in the code about how each CAP can be used. The idea is: - enum pipe_cap is only valid in get_param - enum pipe_capf is only valid in get_paramf Which CAPs are floating-point have been determined based on how everybody except svga implemented the functions. svga have been modified to match all the other drivers. Besides that, the floating-point CAPs are now prefixed with PIPE_CAPF_.
