fonts: Add font variations support for Windows (#38831)

Unlike other platforms where we read the default axis values and combine
it with variations from style to make the font face, we set the
variations from the style when creating the font face and then read the
final variations from the face. It seems that DirectWrite does the
normalization of variation values internally.

This depends on servo/dwrote-rs#68.

Testing: We currently don't have tests for Windows, but variation
support is
covered by the WPT tests.
Fixes: This is part of #38800.
