i2c: Type-state ArmedDma refactor + on-hw abort test Drop the runtime `committed` flag from ArmedDma; commit(self) now consumes the guard via mem::forget, so a committed transfer is no longer a droppable value and Drop tears down unconditionally. Add the two-image i2c_dma_abort hardware test (master DMA + clock-stretching slave) exercising the commit no-op path and the timeout -> guard-drop -> soft-reset teardown path.

NOTE: We are converting our build system to bazel. We recommend installing bazelisk to automatically manage bazel versions.
You can run tasks using the Pigweed workflow launcher pw or bazel.
./pw presubmit - Run presubmit checks: formatting, license checks, C/C++ header checks and clippy../pw format - Run the code formatters.bazel test //... - Run all tests.bazel build //docs - Build documentation.The project is structured as a bazel module.
No additional tools are required - all dependencies are managed by bazel.
