Joey Parrish 9cce246325 Fix TextEngine buffered range calculations ...

This reverts commit c38d4dd8d3, which
actually broke text range calculations in v2.3.10, and v2.4.2-v2.4.4.
The original commit was meant to account for the period start, but
resulted in a double-accounting of presentationTimeOffset.

The start and ends times passed into TextEngine's appendBuffer were
period-relative, so timestampOffset had already been applied.  To
avoid further confusion and to fix the original issue the reverted
commit tried to address, these have been changed to
presentation-relative timestamps.  Now the period start and all
offsets have been accounted for before the metadata reaches
MediaSourceEngine and TextEngine.

The tests added in the bad commit have been modified to test for the
opposite: that we do not erroneously account for timestamp offset when
calculating the buffered ranges for text.

Closes #1562
