Closes the gap #2752's title implies: a generator function EXPRESSION
(function*(k){}) parses as generator_function, which was in neither
_JS_DESCEND_TYPES nor the JS/TS function_boundary_types, so it still fabricated
an indirect_call to a same-named callable. Adds generator_function to both.
Adds a generator-FE regression test and a .tsx test that locks the
_TSX_CONFIG-by-reference coupling (untested before). Full JS/TS indirect_call
/calls regression re-run green (812 passed).
