gallium: add PIPE_CAP_TGSI_ARRAY_COMPONENTS
This is a screen cap because drivers are expected to support it either for all shader types or for none of them. Reviewed-by: Edward O'Callaghan <funfunctor@folklore1984.net> Reviewed-by: Dave Airlie <airlied@redhat.com>

combination will require a driver fallback, and should not be
advertised in the GLX/EGL config list.
+* ``PIPE_CAP_TGSI_ARRAY_COMPONENTS``: If true, the driver interprets the
+ UsageMask of input and output declarations and allows declaring arrays
+ in overlapping ranges. The components must be a contiguous range, e.g. a
+ UsageMask of xy or yzw is allowed, but xz or yw isn't. Declarations with
+ overlapping locations must have matching semantic names and indices, and
+ equal interpolation qualifiers.
+ Components may overlap, notably when the gaps in an array of dvec3 are
+ filled in.
