feat(swaps): Support cross-chain swaps, swap screen redesign

[jophish]

Description

For RET-1065. Adds support for cross-chain swaps, and completes the redesign of the main swap screen.

One consequence of this redesign is that the confirm swap button can no longer be pressed unless a swap is actually possible given the current parameters. This means that several conditional bottom sheets that only appeared upon pressing confirm have been removed from the screen, which is kinda nice. Since there are now a ton of possible inline notifications and their order of precedence was already pretty messy, I've refactored how notifications are handled a bit.

Test plan

Manual and unit tested. See videos below:
