  [Win] Remove the code rounding off glyph advances and offsets
https://bugs.webkit.org/show_bug.cgi?id=228536

Reviewed by Don Olmstead.

Since https://commits.webkit.org/18359@main added the code integrating
with Uniscribe for Windows port, it was rounding off glyph advances
and offsets.

However, this caused layout issues in some web pages especially with
high DPI display.

isSystemFont() method of FontPlatformData class is no longer used for
Windows port. Removed it.
