RustSetupSteps.yml: Update to latest cargo_tarpaulin 31.2 and Rust Toolchain

[antklein]

Update to the latest version of cargo_tarpaulin, release 31.2. This change is required to allow tarpaulin to function with Rust toolchain 1.80. Running tarpaulin 27.3 with toolchain 1.80 results in the tool failing with a "Parse error".

@makubacki and @apop5 Can I get your help reviewing this change?

[apop5]

@antklein If you make these changes locally, does the build succeed? I'm worried there will be other cascading changes needed similar to the tool chain update needing this.

I validated locally for my internal project. Is there a specific repo you want me to test this with? In the mean time, I'll test the same repos I tested before for the toolchain update.

Please run each command in Makefile.toml at least once in one of the repos it is synced to.

I ran the commands for all of the of the repos that sync from mu_devops. I found no issues with running cargo_tarpaulin, however a few of the repositories tests are failing which caused 'coverage' to fail.

Failing because of a dependency changing like the compiler version or a crate update?

For example, mu_rs top of tree I am seeing these failures. This is with toolchain 1.76 and tarpaulin 27.3.

cargo make clippy:

   --> mu_macro\src\lib.rs:126:5
    |
126 |     use proc_macro2;
    |     ^^^^^^^^^^^^^^^^ help: remove it entirely

error: could not compile `mu_macro` (lib test) due to 1 previous error
warning: build failed, waiting for other jobs to finish...
[cargo-make] ERROR - Error while executing command, exit code: 101

cargo make coverage:

Error: "Test failed during run"
[cargo-make] ERROR - Error while executing command, exit code: 1
[cargo-make] WARN - Build Failed.

But the coverage check might be failing because of differences in how cargo test and cargo make test work. On my local system. cargo make test passes, but cargo test fails.

cargo test failure:

Here are the errors I get from tip of main in mu_tiano_platforms.

cargo make clippy:

@antklein Are you comfortable with this going in now?
