vcl: Create accessor and mutator for int and ext leading in FontMetric

Accessor and mutator created for external and internal leading space 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 external and leading space
- check equality operator on FontMetric after setting both external
and internal leading space
- enhanced tests to also check the inequality operator
