* Omit MetaMask `extensionId` from site metadata
The site metadata was updated in #7218 to include the extension id of
the extension connecting to MetaMask. This was done to allow external
extensions to connect with MetaMask, so that we could show the id on
the provider approval screen.
Unbeknownst to me at the time, the extension id was being set for all
connections to MetaMask from dapps. The id was set to MetaMask's id,
because the connections are made through MetaMask's contentscript.
This has been updated to only set the id when accepting a connection
from a different extension.
* Fix `siteMetadata` property names
In #7218 a few things were added to the site metadata, so the provider
approval controller was middleware was updated to accept the site
metadata as an object rather than accepting each property as a separate
parameter. Unfortunately we failed to notice that the site name and
icon were named differently in the site metadata than they were in the
provider approval controller, so the names of those properties were
unintentionally changed in the controller state.
The provider approval controller has been updated to restore the
original property names of `siteTitle` and `siteIcon`. An unused prop
that was added to the provider approval page in #7218 has also been
removed.
If the extension ID is set, an alternate title and subtitle are used
for the Connect Request screen. The title is always `External
Extension`, and the subtitle is `Extension ID: [id]` instead of the
origin (which would just be `[extension-scheme]://[id]` anyway).
The hostname for the site is used as a fallback in case it has no
title.
The artificial hostname set for internal connections has been renamed
from 'MetaMask' to 'metamask' because URL objects automatically
normalize hostnames to be all lower-case, and it was more convenient to
use a URL object so that the parameter would be the same type as used
for an untrusted connection.

* Ensure that the confirm screen renders before the home screen if there are unapproved txs.
* Only render confirm screen before home screen on mount.
