compiler: Rename INTERP_QUALIFIER_* to INTERP_MODE_*.

Likewise, rename the enum type to glsl_interp_mode.

Beyond the GLSL front-end, talking about "interpolation modes" seems
more natural than "interpolation qualifiers" - in the IR, we're removed
from how exactly the source language specifies how to interpolate an
input.  Also, SPIR-V calls these "decorations" rather than "qualifiers".
