* feat: add cargoLlvmCov
* cargoHelperFunctionsHook: prefer `--release` over `--profile release`
Some tools (e.g. cargo-llvm-cov) don't understand `--profile release` as
an alias for `--release`, so `cargoWithProfile` should prefer passing
`--release` when `$CARGO_PROFILE` == "release"

Write a `main.rs` to `src/bin/dummy` within the generated dummy source,
rather than `src/main.rs` to account for `illegalBin` test case

Crates from git repos are vendored in a flattened directory where each crate shows up at the root of the vendor directory. Since the vendoring step effectively breaks workspace structures, any crates which use workspace inheritance (e.g. package.version.workspace = true will fail to resolve.
To work around this we inspect the crate's workspace manifest (if it exists) and attempt to manually merge the values while copying the contents to the vendor directory.
Using `cp --no-preserve mode` ends up losing the executable bit of
previously compiled build scripts. Instead we should ignore the file
ownership, and subsequently make the files writable (since the store is
read only)
* mkDummySrc: also include `no_std` attrs for target_os = uefi
* buildDepsOnly: only check with `--all-targets` if doCheck enabled
* mkDummySrc: allow customizing dummy Rust file contents
* Instead of injecting our own dummy `build.rs` file, we will patch the
`Cargo.toml` files to specify a build script in the Nix store
* This allow cargo to notice the difference (i.e. changed build script
path) where it could not before (due to nix enforcing that all sources
always have the same timestamp)
This is done to avoid breaking builds by including puts happen to have
setup-hooks which try to claim the configure phase (such as `cmake`).
The old behavior can be brought back by setting `configurePhase = null;`
on the derivation.
* Seems like cargo-audit only needs a `Cargo.lock` file and an advisory
database to run, so we can filter the inputs down even further to
avoid rebuilds and file copying into the Nix sandbox
* This allows for fewer assumptions about the project structure
* The old behavior can easily be brought back by setting `cargoExtraArgs
= "--workspace";` in any derivation
