  Introduce a <model> loading process - Part 3
https://bugs.webkit.org/show_bug.cgi?id=243874
rdar://122051588 (Create new com.apple.WebKit.Model process)

Reviewed by Elliott Williams.

Added Xcode target for the actual ModelProcess XPC service.
Added sandbox profile (which inherits directly from WebProcess for now).
Actually trigger the launching of the process when <model> tag is present
when the user enables the ModelProcess path.
Stops the existing UIProcess based rendering path when the user enables
ModelProcess path.

* .gitignore:
Removed a rule that doesn't seem to apply to anything recent Xcode generates.
Having it around makes git ignore the model process sandbox profile unexpectedly.
