[Site Isolation] Navigation to about:blank inherits navigator's origin
https://bugs.webkit.org/show_bug.cgi?id=302102
rdar://160706600
Reviewed by Alex Christensen.
If an iframe is navigated to about:blank, it should inherit the origin
of whoever initiated the navigation.
With site isolation, this means that the about:blank iframe needs to
be in the same process as the navigator. If the iframe was previously
in a different origin than the navigator, this might require a process
swap.
This patch also attempts to perform these loads to about:blank "immediately"
by committing a provisional frame right after creating one since about:blank
iframes don't have any network resources to load.
