Restore support for Chromium v78 (#17251)
Support has been restored for Chromium v78. Previously the extension
would crash upon startup.

The main incompatibility was the use of ES2020 operators (the optional
chain and nullish coalesce operators) in the libraries
 `@ethereumjs/util` and `superstruct`. This was resolved by transpiling
those libraries.

After fixing that, the extension no longer crashed but the UI refused
to connect. This was because the UI process was not being identified as
an internal process, because the code responsible for checking that was
relying on the `origin` property of `MessageSender` [1] which wasn't
added until Chromium v80. The check has been updated to use the `url`
property instead, which existed in older versions of Chrome.

Lastly, the content security policy was updated to include the default
content security policy alongside the intended modification. Newer
versions of Chrome will merge the configired CSP with the default, but
older versions required it to be explicitly specified. This should not
result in any functional change.
