glsl: use enum glsl_interface_packing in more places. (v2)

Although the glsl_types.h stores this in a bitfield,
we should hide that from everyone else. Hide the cast
in an accessor method and use the enum everywhere.

This makes things a bit nicer in gdb, and improves type
safety.

v2: fix a few pieces of interface I missed that caused some
piglit regressions.
