  [compression] Brotli: correctly handle large output when flushing
https://bugs.webkit.org/show_bug.cgi?id=285443
rdar://problem/142424257

Reviewed by Alex Christensen.

During the finalize step, the internal buffer of Brotli has the potential to be holding more data than what our buffer can hold.
Therefore we will need to continue to request Brotli for more data, so we do not truncate the results.
