Implement builtin#format_args, using rustc's format_args parser
`format_args!` now expands to `builtin#format_args(template, args...)`, the actual expansion now instead happens in lowering where we desugar this expression by using lang paths.
As a bonus, we no longer need to evaluate `format_args` as an eager macro which means less macro expansions overall -> less cache thrashing!

Add a few more `db.unwind_if_cancelled()` calls
Judging from a profile sent by a friend, the borrowck query took up a significant amount of time in their project which might be the cause for some unresponsiveness as nothing in the mir stack currently unwinds on cancellation
Shuffle some locking around
The main thread is still occasionally blocking on something and I am unsure what the cause might be. This will hopefully help somewhat
Fix cargo handle logging in flycheck
This PR has two commits, so it's probably easier to review them separately:
(1) Rename `CargoHandle` to `CommandHandle`, as the command may not be a cargo command.
(2) Logging should format the current command, rather than calling `check_command()` again. This ensures that any later configuration changes don't cause us to log incorrect information.
proc-macro-test: Pass target to cargo invocation
When cross compiling macos → dragonfly the dist build fails in the proc-maro-test-impl crate with the following error:
`ld: unknown option: -z\nclang: error: linker command failed with exit code 1 (use -v to see invocation)`
This appears to be a wart stemming from using an Apple host for cross compiling. Passing the target along to cargo allows it to pick up a linker that it understands and DTRT.
Previously this was hard coded to "0.1". The SCIP protocol allows this
to be an arbitrary string:
```
message ToolInfo {
// Name of the indexer that produced this index.
string name = 1;
// Version of the indexer that produced this index.
string version = 2;
// Command-line arguments that were used to invoke this indexer.
repeated string arguments = 3;
}
```
so use the same string reported by `rust-analyzer --version`.
Warn on elided lifetimes in associated constants (`ELIDED_LIFETIMES_IN_ASSOCIATED_CONSTANT`)
Elided lifetimes in associated constants (in impls) erroneously resolve to fresh lifetime parameters on the impl since #97313. This is not correct behavior (see #38831).
I originally opened #114716 to fix this, but given the time that has passed, the crater results seem pretty bad: https://github.com/rust-lang/rust/pull/114716#issuecomment-1682091952
This PR alternatively implements a lint against this behavior, and I'm hoping to bump this to deny in a few versions.
fix help text for rust-analyzer.check.invocation{Strategy,Location}
I highly doubt that `check.invocationLocation` only has an effect if `cargo.buildScripts.overrideCommand` is set -- looks like a copy-paste mistake from `buildScripts.invocationLocation` to me.
