[PATCH 1/3] msvcrt/tests: Test wcstoi64 with various Unicode digits.

[Lauri Kenttä]

The list of possible Unicode zeros was found here:
https://unicode-table.com/en/search/?q=%22digit+zero%22
Then I removed those that didn't work in Windows.

"CJK Ideograph, First" is interesting test case because it could be
read as 1 (in theory) but it isn't.

The two other added test strings are interesting because they show
that different kinds of digits may be mixed and that hex/oct prefix
(0x or 0) works even if the 0 is not ASCII (here tested with THAI).
