THP Rust library

[mmilata]

Tracking issue.

Major parts:

• crypto primitives Rust bindings for trezor-crypto primitives needed by THP #6140
  • drop unused things like CRC32
• transport layer rust/trezor-thp: transport layer #6195
• secure channel - host rust/trezor-thp: secure channel layer - host side #6339
• secure channel - device rust/trezor-thp: secure channel layer - device side #6450
• implement ACK piggybacking, see Implement THP ACK piggybacking #6135 rust/trezor-thp: ACK piggybacking #6791
• replace python implementation in firmware [draft] Switch THP implementation to rust/trezor-thp #6676
• integration with trezor-client
• C API (for Monero support)

Known issues and missing parts:

• make sure sensitive data are zeroized
• fix behaviour on ACK loss rust/trezor-thp: ACK piggybacking #6791
• send DECRYPTION_FAILED messages (device side only) rust/trezor-thp: minor improvements #6790
• avoid allocating colliding channel ids like python implementation does [1] rust/trezor-thp: minor improvements #6790
• ensure good test coverage, possibly using https://crates.io/crates/cargo-tarpaulin
