[MSE] Reuse "fudge factor" when samples are removed
https://bugs.webkit.org/show_bug.cgi?id=258869
Reviewed by Xabier Rodriguez-Calvar.
Currently when TrackBuffer::removeSamples is called and erasedRanged is created
from the samples,
removing small gaps between samples is not done. It causes that in some cases
many separated ranges
are created which has impact on performance of removing samples.
Reusing "eliminate small gap" mechanism from
SourceBufferPrivate::processMediaSample solves the problem.
