Delete confirm-token-transaction-switch component

Component [confirm-token-transaction-switch](https://github.com/MetaMask/metamask-extension/blob/develop/ui/pages/confirm-transaction/confirm-token-transaction-switch.js) takes care to get token relates data from using selectors and other hooks and rendering token routes passing this data. We need to do following refactor:

1. Minimise props passing from confirm-token-transaction-switch. This can be done by getting this data directly in `confirm-approve` and `confirm-token-transaction-base` components. Both of these are functional components. Only 1 prop `transaction` should be required to pass down to various components.

2. Move the 5 routes mapping to `/pages/confirm-transaction.component.js`

3. Add more unit test coverage here `/pages/confirm-transaction.test.js` for the 5 routes added to it

4. Delete `/pages/confirm-token-transaction-switch.js`

Start by reading ui/pages/confirm-transaction/confirm-token-transaction-switch.js, then inspect confirm-approve, confirm-token-transaction-base, and /pages/confirm-transaction.component.js. Run the tests in /pages/confirm-transaction.test.js before changing the five route mappings. Done means the switch component is deleted, only transaction is passed where required, routes are moved, and coverage is added for all five routes.
