Converted all `rust-toolchain` files to the more expressive `rust-toolchain.toml` format.

Converted all `rust-toolchain` strings to `rust-toolchain.toml`.
kkysen
committed
Fixed a read of `rust-toolchain.toml` that reads the toolchain channel using the `toml` library to parse.
kkysen
committed
Added the `rustup` components to the `rust-toolchain.toml` file.
kkysen
committed
Updated the `rust-toolchain.toml` in an example to match the root `rust-toolchain.toml`. I believe they should be in sync because this one is produced by copying the root one.
kkysen
committed
Clarified that we need the channel not the contents of the `rust-toolchain.toml` file now.
kkysen
committed
Deleted duplicate `RUST_VER` parsing in `provision_mac.sh`.
kkysen
committed
Refactored the `rust_toolchain.toml` `toolchain.channel` lookup into `query_toml.py`, which is also a CLI and is used in `docker_build.sh` and `provision_mac.sh` to query the channel now.
kkysen
committed
Updated to parsing `rust-toolchain.toml` in `c2rust-instrument` using `toml-edit` (as `cargo` does).
kkysen
committed
Removed unused Python imports.

Fixed bad import path.
