vcl: Create accessor and mutator for ascent and descent in FontMetric

Accessor and mutator created for ascent and descent spacing in
FontMetric.

See commit description in 8bfccd3a71d911b6d ("vcl: Create accessor
and mutator for font scaling in FontMetric") for reasoning behind
patch.

Unit tests
- check to ensure that can set font ascent and descent spacing
- check equality operator on FontMetric after setting both ascent
and descent font spacing
