3814: Add impl From for enum variant assist r=flodiebold a=mattyhall
Basically adds a From impl for tuple enum variants with one field. It was recommended to me on the zulip to maybe try using the trait solver, but I had trouble with that as, although it could resolve the trait impl, it couldn't resolve the variable unambiguously in real use. I'm also unsure of how it would work if there were already multiple From impls to resolve - I can't see a way we could get more than one solution to my query.
Fixes #3766

Use the trait solver to check if there's an existing implementation of
From<type_in_enum_variant> for the enum.

Basically adds a From impl for tuple enum variants with one field. Added
to cover the fairly common case of implementing your own Error that can
be created from another one, although other use cases exist.

3816: vscode: add goto ast node definition from rust source code r=Veetaha a=Veetaha
By holding the `Ctrl` key you can now goto-definition of the appropriate syntax token in the syntax tree read-only editor. But actually going to the definition is not very convenient, since it opens the new editor, you'd rather just hold the `Ctrl` and look at the syntax tree because it is automatically scrolled to the proper node and the node itself is enclosed with text selection.
Unfortunately, the algorithm is very simple (because we don't do any elaborate parsing of the syntax tree text received from the server), but it is enough to debug not very large source files.
I tested the performance and in a bad case (rust source file with 5K lines of code) it takes `1.3` seconds to build the `rust -> ast` mapping index (lazily once on the first goto definition request) and each lookup in this worst-case is approx `20-120` ms. I think this is good enough. In the simple case where the file is < 100 lines of code, it is instant.
One peculiarity that I've noticed is that vscode doesn't trigger the goto-definition provider when the user triggers it on some punctuation characters (i.e. it doesn't underline them and invoke te goto-definition provider), but if you explicitly click `Ctrl+LMB` it will only then invoke the provider and navigate to the definition in a new editor. I think this is fine ;D

3819: Unique package by name and version. r=matklad a=o0Ignition0o
This commit is a fixup of #3781 I introduced a bug by using a PackageId to refer to a crate when its name conflicts with a dependency.
It turns out the package id currently is `name version path` while cargo expects `name:version` as argument eg:
Cargo command with a `PackageId`:
```
> Executing task: cargo test --package 'config 0.1.0 (path+file:///Users/ignition/Projects/oss/config)' --test default -- test_with_name --exact --nocapture <
```
Cargo command with `name:version`:
```
> Executing task: cargo test --package 'config:0.1.0' --test default -- test_with_name --exact --nocapture <
```

3817: vscode: highlight syntax tree ro editor r=matklad a=Veetaha
Small textmate grammar declaration to make rust-analyzer syntax tree more easily inspectable:
Btw, if we change the file extension of our `ra_syntax/test_data/**` files to `.rast` they should be highlighted in vscode too.
The colors of the tokens are actually going to be color-theme dependent, or you can customize them via:
```jsonc
{
"editor.tokenColorCustomizations": {
"textMateRules": [ { "scope": "name", "settings": { /* */ } } ]
}
}
```

3806: lower bool literal value r=flodiebold a=JoshMcguigan
Following up on #3805, this PR adds the literal value to `ast::LiteralKind` so when we lower we can use the actual value from the source code rather than the default value for the type. Ultimately I plan to use this for exhaustiveness checking in #3706.
I didn't include this in the previous PR because I wasn't sure if it made sense to add this information to `ast::LiteralKind` or provide some other mechanism to get this from `ast::Literal`.
For now I've only implemented this for boolean literals, but I think it could be easily extended to other types. A possible exception to this are string literals, since we may not want to clone around an owned string to hold onto in `ast::LiteralKind`, and it'd be nice to avoid adding a generic lifetime as well. Perhaps we won't ever care about the actual value of a string literal?
