Jan Pochyla 6257584951 feat(core): Add Rust bindings to MicroPython and trezorhal
core: Remove dangling module decls

core: Use new Cargo feature resolver, use external MacOS debug info

core: Rust docs improvements

core: Upgrade bindgen

core: Add test target to Rust

ci: build rust sources

build(core): .ARM.exidx.text.__aeabi_ui2f in t1 firmware size

It's an unwind table for softfloat function inserted by rustc, probably
can be removed to save 8 bytes:
599c58db70/link.x.in (L175-L182)

scons: Remove dead code

core: Move Rust target to build/rust

core: Replace extern with a FFI version

core: Add some explanatory Rust comments

core: Use correct path for the Rust lib

core: Remove Buffer::as_mut()

Mutable buffer access needs MP_BUFFER_WRITE flag. TBD in the Protobuf PR.

core: Improve docs for micropython::Buffer

core: Minor Rust docs changes

core: Rewrite trezor_obj_get_ll_checked

core: Fix incorrect doc comment

core: Remove cc from deps

fixup! core: Rewrite trezor_obj_get_ll_checked

core: update safety comments
