Add StreamBatched to ReleaseDisplayList IPC Message

Reviewed by Kimmo Kinnunen.
Add StreamBatched to ReleaseDisplayList IPC message.
This batches ReleaseDisplayList IPC messages, accumulating 100
messages on the WebContent process client side
before calling semaphore_signal_trap() to wake
the GPU process to delete a GlyphDisplayList cache
entry.
This is a performance optomization that reduces
the number semaphore signals. This is a
bottleneck seen in LayoutIntegration::InlineContent::~InlineContent()
which calls GlyphDisplayListCache::remove() frequently.
StreamBatched was previously used for ReleaseDecomposedGlyphs
(see https://commits.webkit.org/292098@main) but was
not added to the replacement ReleaseDisplayList message in
https://commits.webkit.org/299747@main. This restores
the batching optimization.
