fonts: Rework platform font initialization (#32127)
This change reworks the way that platform fonts are created and
descriptor data is on `FontTemplate` is initialized.

The main change here is that platform fonts for local font faces are
always initialized using the font data loaded into memory from disk.
This means that there is now only a single path for creating platform
fonts.

In addition, the font list is now responsible for getting the
`FontTemplateDescriptor` for local `FontTemplate`s. Before the font had
to be loaded into memory to get the weight, style, and width used for
the descriptor. This is what fonts lists are for though, so for every
platform we have that information before needing to load the font. In
the future, hopefully this will allow discarding fonts before needing to
load them into memory. Web fonts still get the descriptor from the
platform handle, but hopefully that can be done with skrifa in the
future.

Thsese two fixes together allow properly loading indexed font variations
on Linux machines. Before only the first variation could be
instantiated.
