Android: glsl: add rules to generate ir_expression*.h header files

Recent changes to generate ir_expression*.h header files broke Android
builds. This adds the generation rules. This change is complicated due to
creating a circular dependency between libmesa_glsl, libmesa_nir, and
libmesa_compiler. Normally, we add static libraries so that include paths
are added even if there's no linking dependency. That is the case here.
Instead, we explicitly add the include path using $(MESA_GEN_GLSL_H) to
libmesa_compiler. This in turn requires shuffling the order of make
includes. It also uncovered missing dependency tracking of glsl_parser.h.
