gh19010: fix returns for Perl_grok_infnan
Consistently honour what the docs have always promised:
If an infinity or a not-a-number is recognized, C<*sp> will point to
one byte past the end of the recognized string. If the recognition fails,
zero is returned, and C<*sp> will not move.
Additionally, restore Perl_grok_number_flags to allowing inf/nan with
trailing garbage only when called with PERL_SCAN_TRAILING; add notes
to the other two core callers to clarify that they always accept such
trailing garbage.
Whitespace handling is regularized: trailing whitespace after anything
successfully parsed is always accepted, and does not trigger setting
IS_NUMBER_TRAILING.
A small number of XS-APItest tests were modified to reflect the stricter
behaviour: "Infin" and "nanx" are now invalid without PERL_SCAN_TRAILING.
An additional inconsistency (GH #19464) is commented in the tests but
not addressed here.
