fonts: Use fontations to read the OS/2 table of DirectWrite fonts (#38851)

Instead of copying the font table data in memory and parsing it with the
`truetype` crate, use a non-copying API from DirectWrite to implement a
`fontations` `TableProvider`. This has two benefits:

- We remove the dependency on the `truetype` crate finally.
- We do not have to make an in-memory copy of the table data when
  parsing the table.

The hope is that the `TableProvider` will be more generally useful in
the future.

Testing: There are no automated tests for Windows, but I manually
verified
that the data retrived via `fontations` matched that retrived by
`truetype`.
