Now checks if the current token is `.` and inserts `.Default::default()` if it is, so `..Default::default()` is correctly completed.

In short, the goal of this MR is to allow rust-analyzer to discover proc-macros which come from your tests (including, most importantly, dev-dependencies). By default, `cargo check` implies the equivalent of `--lib --bins`, meaning it'll check your libraries and binaries -- but not tests! This means proc-macros (or, I guess, build scripts as well) weren't discovered by rust-analyzer if they came from tests. One solution would be to manually add `--lib --bins --tests` (i.e., just augment the effective options to include tests). However, in this MR, I threw in `--all-targets`, which [according to the docs](https://doc.rust-lang.org/cargo/commands/cargo-check.html#target-selection) implies `--benches --examples` too. I have absolutely no idea what repercussions that will have on rust-analyzer for other projects, nor do I know if it's a problem that build scripts will now be discovered for tests/examples/benches. But I am not aware of a reason you _wouldn't_ want to discover these things in your examples too. I think the main drawback of this change is that it will likely slow down the `cargo check`. At a minimum, it'll now be checking your tests _and_ their dependencies. The `cargo check` docs also say that including `--tests` as I have here may cause your lib crate to be built _twice_, once for the normal target and again for unit tests. My reading of that caveat suggests that "building twice" means it's built once for the tests _inside_ your lib, with a test profile, and again for any consumers of your lib, now using a normal release profile or similar. This doesn't seem surprising. Very minor caveat: `--tests` will not include tests within a binary if it has `test = false` set in `Cargo.toml`. (I discovered this manually by trial-and-error, but hey, it actually says that in the docs!) This is likely not an issue, but _does_ mean that if you are -- for whatever reason -- disabling tests like that and then manually specifying `cargo test --package <...> --bin <...>` to run them, rust-analyzer will remain unaware of proc-macros in your tests. I have confirmed this fixes the original issue in my sandbox example linked in #7034 and in my own project in which I originally discovered this. I've left it configured as my default RA language server and will report back if I notice any unexpected side-effects. Fixes #7034 Co-authored-by: Kaelin Laundry <[email protected]>

In theory we ought to memoise the attempts (both the `--help` and the installation) so that we don't keep retrying something which will fail (e.g. if nightly is missing rustfmt), but this is a first-pass for opinions. In order to make it possible to notify the user of what happened, I added a facility for `GlobalStateSnapshot` to send *messages* to the client indicating what happened. There may be a cleaner way to do this as well but I wasn't sure exactly what might be best given this is my first time in this codebase. It may be worth, longer term, working with `rustup` to provide a way to detect a missing component binary since `rustup` returns `1` if `rustfmt` is not installed, which is not ideal.

In theory this ought to be memoised but for now it'll do as-is. Future work might be to ask the user if they would like us to trigger the installation (if possible).
