nir: Delete open coded type printing.

glsl_print_type() prints arrays of arrays incorrectly.  For example,
a type with name float[3][7] would be printed as float[7][3].  (This
is an array of length 3 containing arrays of 7 floats.)  cdecl says
that the type name is correct.

glsl_print_type() doesn't really do anything above and beyond printing
type->name, and glsl_print_struct() wasn't used at all.  So, drop them.
