feat: TXE 2: Electric boogaloo (#7154)

Adds new capabilities to TXE, and a proper `TokenContract` suite to
showcase them:

- Private -> Public calls
- Public -> Public calls
- Actual account contract deployment for complex interactions
- Auhtwits, both public and private
- Note cache storage
- Speed improvements

The full test suite is comparable to the e2e one (with some caveats,
some things just cannot be tested yet using TXE), but runs significantly
faster. Interestingly, runs faster on an M3 macbook than on mainframe
(120s vs. 240s).

e2e tests take more than 600s (without stored snapshots), but the gap
increases as we reduce the amount of tests launched simultaneously. An
unconstrained private transfer runs in less than 10s using TXE!

If launching many tests in parallel, it is recommended to increase the
nargo timeout for foreign calls to avoid timeout errors:
`NARGO_FOREIGN_CALL_TIMEOUT=300000`

Closes #7086
