[ledger integration] add ledgerjs-hw-app-sui library as an SDK (Myste…

…nLabs#8788)

## Description 

This PR adds the `ledgerjs-hw-app-sui` library from Obsidian as an SDK
under our repository since we'll be maintaining and owning it going
forward. I changed around and added some project configurations (e.g.
ESLint, Prettier, Vitest, etc.), but all of the code is pretty much
strictly copy and pasted over. I confirmed with the Obsidian team that
it's okay to move this code over and apply our software licenses.

There are some improvements and clean-up to be done in the SDK itself,
but I figure this is a good starting point since it's at least in a
working state. As follow-ups, we'll do some KTLO work to get the library
in better shape and add more comprehensive test coverage (i.e., unit
tests and E2E tests that interact with
[Speculos](https://github.com/LedgerHQ/speculos)).


## Test Plan 
- All `npm` scripts run successfully
