-----------
Add possibility to use large strings in WebPage::runJavaScript without copies
https://bugs.webkit.org/show_bug.cgi?id=303295
rdar://165603388
Reviewed by Ben Nham.
Add IPC::TransferString to support explicit serialization of large
strings. In subsequent patches, this will be used to pass large JS
strings as memory that is shared between multiple WebContent processes.
Avoids extra NSString * -> wtf::String copy that was done only to
send the string via IPC.
To be conservative, the feature is added as explicit TransferString
instead of being built-in to IPC string serialization. If the feature
turns out to be non-problematic and receive-side API issues are solved,
it may be merged as the default String serialization.
