fix: Readd cancel and speed up transaction modal

[pedronfigueiredo]

Description

On #29884, a lot of code related to MetaMask Institutional was removed.

The <CancelSpeedupPopover /> component was removed, probably because it was conditionally rendered when a custodian was not present (for non-MMI code only), and someone mechanically removing code might have thought it wasn't needed anymore. What we wanted to do instead was to remove the condition and render the modal unconditionally.

This PR reintroduces the component.

Manual testing steps

1. Submit a transaction with low gas parameters
2. Once it is pending, speed up or cancel it from the activity list
