Reduce IPC data sent over getMappedRange
https://bugs.webkit.org/show_bug.cgi?id=306535
rdar://169187911
Reviewed by Dan Glastonbury.
Instead of sending the entire buffer contents across IPC and then
calling subspan() on it in the web content process, only send the
subset across IPC and then assume the web content process receives
the subset of the contents.
