refactor: clean up webFrame implementation to use gin wrappers (#28497)
* refactor: clean up webFrame implementation to use gin wrappers

The previous implementation of webFrame in the renderer process leaked
sub-frame contexts and global objects across the context boundaries thus
making it possible for apps to either maliciously or accidentally
violate the contextIsolation boundary.

This re-implementation binds all methods in native code directly to
content::RenderFrame instances instead of relying on JS to provide a
"window" with every method request.  This is much more consistent with
the rest of the Electron codebase and is substantially safer.

* chore: un-re-order for ease of review

* chore: pass isolate around instead of ErrorThrower

* chore: fix rebase typo

* chore: remove unused variables
