regen/embed.pl: Generally generate an ARGS_ASSERT

Prior to this commit, if you changed a pointer argument to allow it
being a NULL, you had to go in and also remove the function's
PERL_ARGS_ASSERT macro call.  Now, such macros are generally defined
even if they are empty, so you can add such a call to any function, and
it will always compile.  If there is no assertion needed, the macro
expands to nothing.

Thus now, the use of these macros is optional when no assert is needed;
but still required by the porting test args_assert.t when an assert is
needed.

The generation of such a macro (when its use is optional) can be
suppressed for individual entries by the new G flag in embed.fnc, also
added by this commit.
