Add token selection to the send screen (#6445)
* Move send to pages/
* Fix unit tests
* Finish UI
* Integrate asset dropdown to send actions
* Remove console.log
* Hide asset change during edit
* Enable switch from send token to seand eth
* Enable switching from token to eth when editing
* Fix linter
* Fixing test
* Fix unit tests
* Fix linter
* Fix react warning; remove console.log
* fix flat test
* Add metrics
* Address code review comments
* Consistent spacing between send screen form rows.
* Reduce height of gas buttons on send screen.
* Make send screen gas button height dependent on size of contents.
