Because the `rustc-echo-wrapper` is compiled to `not-target/debug/rustc-echo-wrapper`.
This is resolved by forcing the target-dir to be a manifest-relative one for this specific build.

resolver docs: link to version requirements syntax full explanation
Staring at https://doc.rust-lang.org/cargo/reference/resolver.html#semver-compatibility, I was confused was this is a "refresher" for. Let's add a link to the main documentation this summarizes.
Since the word "xtask" is rather difficult to type in my opinion (at least my left hand struggles quite a bit) I wanted to add another alias, `x` as a shorthand (similar to what `build`, `run`, etc. have by default). Thereby I discovered that I needn't replicate the whole alias, because aliases are recursive. I consulted the docs and couldn't find a mention of this, hence I'm adding it as part of this PR so other users can discover it.
### How should we test and review this PR?
I don't think this requires a separate test, it's a minor change to the documentation only.

Fix formats_source test requiring rustfmt.
The requirements added in #9892 that `rustfmt` must be present doesn't work in the `rust-lang/rust` environment. There are two issues:
* Cargo is run without using rustup. If you also have rustup installed, the test will fail because the `rustfmt` binary found in `PATH` will fail to choose a toolchain because HOME points to the sandbox home which does not have a rustup configuration.
* rust-lang/rust CI uninstalls rustup, and does not have rustfmt in PATH at all. It is not practical to make rustfmt available there.
The solution here is to just revert the behavior back to where it was where it checks if it can run `rustfmt` in the sandbox. This should work for anyone who has a normal rustup installation (including Cargo's CI). If running the testsuite without rustup, then the test will be skipped.
This also includes a small enhancement to provide better error information when rustfmt fails.
The test `scrape_examples_complex_reverse_dependencies` no longer works on the latest nightly. It fails with the error:
```

Auto merge of #9892 - ehuss:cargo_test-ignore-reason, r=weihanglo
Add requirements to cargo_test.
This extends the `#[cargo_test]` attribute to support some additional requirements to control whether or not a test can run. The motivation for this is:
* Can more clearly see when a test is disabled when it prints "ignored"
* Can more easily scan for disabled tests when I do version bumps to see which ones should be enabled on stable (to pass on CI).
The form is a comma separated list of requirements, and if they don't pass the test is ignored. The requirements can be:
* `nightly` — The test only runs on nightly.
* `>=1.55` — The test only runs on rustc with the given version or newer.
* `requires_git` — Requires the given command to be installed. Can be things like `requires_rustfmt` or `requires_hg`, etc.
This also enforces that the author must write a reason why it is ignored (for some of the requirements) so that when I look for tests to update, I know why it is disabled.
This also removes the `CARGO_TEST_DISABLE_GIT_CLI` option, which appears to no longer be necessary since we have migrated to GitHub Actions.

Override to resolver=1 in published package
As discussed in #10112 this avoids inconsistent dependency resolution in development and packaged builds when an edition 2021 crate is published from a workspace using the default resolver=1.
This is done in the command, rather than in the op,
- To consistently construct the `Workspace`
- It is more composable as an API
A downside is we update the git dependencies a second time and any sources we didn't initially update.
Unlike the proposal in the attached issue, this does not roll back on error.
- For some errors, the user might want to debug what went wrong. Losing the intermediate state makes that difficult
- Rollback adds its own complications and risks, including since its
non-atomic
We've already tried to address most potential errors during `cargo add`s processing. To meet this desire, we now error if `--locked` is passed in and we would change the manifest. See that individual commit's message for more details.

This changes the test for an empty RUSTC_WRAPPER environment variable to make it explicit that it doesn't just ignore the environment variable, but that it also essentially unsets any config-loaded value.

refactor(source): Open query API for adding more types of queries
### What does this PR try to resolve?
This refactors the Source/Registry traits from accepting a `fuzzy: bool` to accepting an enum so we can add alternative query styles in the future, as discussed in the Cargo team meeting for fixing #10729
The expected fix for `cargo add` at this point would be
- Add `QueryKind::Normalized`
- Initially, we can make it like Exact for path sources and like Fuzzy for registry sources
- Switch cargo-add to using that kind everywhere (both where `Exact` and `Fuzzy` are used)
- A test to ensure this fixed it
- Rename `Fuzzy` to `Alternatives` or something to clarify its actual intent
### How should we test and review this PR?
The refactor is broken down into multiple commits, so ideally review a commit at a time to more easily see how it evolved.
### Additional information
Future possibilities
- Supporting normalized search on all sources
- Doing version / source matching for normalized results (probably not needed for cargo-add but will make the API less surprising for future users)
