Allow rust-project.json to include arbitrary shell commands for runnables
This is a follow-up on #16135, resolving the feedback raised :)
Allow rust-project.json to include shell runnables, of the form:
```
{
"build_info": {
"label": "//project/foo:my-crate",
"target_kind": "bin",
"shell_runnables": [
{
"kind": "run",
"program": "buck2",
"args": ["run", "//project/foo:my-crate"]
},
{
"kind": "test_one",
"program": "test_runner",
"args": ["--name=$$TEST_NAME$$"]
}
]
}
}
```
If these runnable configs are present for the current crate in rust-project.json, offer them as runnables in VS Code.
This PR required some boring changes to APIs that previously only handled cargo situations. I've split out these changes as commits labelled 'refactor', so it's easy to see the interesting changes.
Support hovering limits for adts
Fix#17009
1. Currently, r-a supports limiting the number of struct fields displayed when hovering. This PR extends it to support enum variants and union fields. Since the display of these three (ADTs) is similar, this PR extends 'hover_show_structFields' to 'hover_show_adtFieldsOrVariants'.
2. This PR also resolved the problem that the layout of ADT was not restricted by display limitations when hovering on the Self type.
3. Additionally, this PR changes the default value of display limitations to `10` (instead of the original `null`), which helps users discover this feature.
* Added config `runnables.extraTestBinaryArgs` to control the args.
* The default is `--show-output` rather than `--nocapture` to prevent
unreadable output when 2 or more tests fail or print output at once.
* Renamed variables in `CargoTargetSpec::runnable_args()` for clarity.

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.)
