d9926edb2f ttf: enhance UWP portability with alternative file loading 
Enhances the portability of the TTF loader on UWP platforms
by implementing an alternative file loading mechanism.

This is designed to support environments where the file mapping
feature is not available, ensuring wider compatibility and reliability
in file handling.
