feat: Add `rust-analyzer.cargo.allTargets` to configure passing `--all-targets` to cargo invocations
Closes#16859
## Unresolved question:
Should this be a setting for build scripts only ? All the other `--all-targets` I found where already covered by `checkOnSave.allTargets`
Refactor extension to support arbitrary shell command runnables
Currently, the extension assumes that all runnables invoke cargo. Arguments are sometimes full CLI arguments, and sometimes arguments passed to a cargo subcommand.
Refactor the extension so that tasks are just a `program` and a list of strings `args`, and rename `CargoTask` to `RustTask` to make it generic.
(This was factored out of #16135 and tidied.)
feat: Support multiple tab stops for completions in VSCode
Uses the native VSCode support for `SnippetTextEdit`s. Fixes#13229 and fixes#8531.

This is done in a slightly hacky way, as `vscode-languageclient` can't convert RA's `SnippetTextEdit`s into vscode `SnippetTextEdit`s and will appear to use a [different format](295aaa393f/types/src/main.ts (L1501-L1516)) in the future.

~~Marked as draft since as-is, this will cause completions to double-indent any multi-line code generated.~~
**Update:** This also fixes up edits so that any multi-line code won't be double-indented.
We can't tell vscode to not add in the extra indentation, so we instead opt to remove it from the edits themselves, and then let vscode add it back in.
fix: Fix build scripts not being rebuilt in some occasions
Also makes proc-macro changed flag setting async, we don't wanna block `process_changes` on the database as that is on the main thread!
Substitute $saved_file in custom check commands
If the custom command has a $saved_file placeholder, and we know the file being saved, replace the placeholder and run a check command.
If there's a placeholder and we don't know the saved file, do nothing.
This is a simplified version of #15381, which I hope is easier to review.
If the custom command has a $saved_file placeholder, and we know the
file being saved, replace the placeholder and then run a check command.
If there's a placeholder and we don't know the saved file, do nothing.
