fonts: Measure more FontContext heap usage. (#38733)

Replace a hand-written MallocSizeOf implementation with an automatically
derived one. This exposes more than 1MB of previously-untracked heap
data on servo.org.

Testing: Compared about:memory output for servo.org before and after.
Part of: #11559
