Add FXSYS_IsUpperASCII().

Add FXSYS_IsUpperASCII() to check whether a character is an uppercase
ASCII letter.

This is a follow-up CL for
https://pdfium-review.googlesource.com/65752/. This new function helps
limit IsStrUpper() to only check for uppercase ASCII letters instead of
all uppercase Unicode characters.

This CL adds more callers for FXSYS_IsUpperASCII() to replace all
uppercase ASCII character checks across PDFium and adds a matching unit
test for the function.
