fortran: Fix up TYPE_ARG_TYPES of procs with scalar VALUE optional args [PR92305]

The following patch fixes
-FAIL: libgomp.fortran/use_device_addr-1.f90   -O0  execution test
-FAIL: libgomp.fortran/use_device_addr-2.f90   -O0  execution test
that has been FAILing for several months on powerpc64le-linux.
The problem is in the Fortran FE, which adds the artificial arguments
for scalar VALUE OPTIONAL dummy args only to DECL_ARGUMENTS where the
current function can see them, but not to TYPE_ARG_TYPES; if those functions
aren't varargs, this confuses calls.c to pass the remaining arguments
(which aren't named (== not covered by TYPE_ARG_TYPES) and aren't varargs
either) in a different spot from what the callee (which has proper
DECL_ARGUMENTS for all args) expects.  For the artificial length arguments
for character dummy args we already put them in both DECL_ARGUMENTS and
TYPE_ARG_TYPES.

	PR fortran/92305
	* trans-types.c (gfc_get_function_type): Also push boolean_type_node
	types for non-character scalar VALUE optional dummy arguments.
	* trans-decl.c (create_function_arglist): Skip those in
	hidden_typelist.  Formatting fix.
