1984: Bump rollup and vsce r=matklad a=kjeremy
I got sick of the vsce warning on install and noticed that rollup was also out of date.

The old `vscode` package is outdated and it is recommened to switch to
these two new packages. This also solves a problem of a missing `.d.ts`
for `vscode` in Nixos.
1652: Improve type hints behavior r=matklad a=SomeoneToIgnore
This PR fixed the following type hints issues:
* Restructures the `InlayKind` enum contents based on the discussion here: https://github.com/rust-analyzer/rust-analyzer/pull/1606#issuecomment-515968055
* Races described in #1639
* Caches the latest decorations received for each file to show them the next time the file is opened (instead of a new server request)

1458: Run VS Code tests on CI r=matklad a=etaoins
This is actually much faster than I expected; it takes about 13 seconds to download VS Code and run the unit tests. This means the VS Code tests are still significantly faster than the Rust ones.
If this ends up being unreliable we can always remove it later or move it to a separate optional job.
We also need to ignore the `.vscode-test` directory when running `prettier` or it will get upset about some temporary JSON files VS Code creates.

1459: Include primary span label in VS Code diagnostics r=matklad a=etaoins
In most cases the primary label span repeats information found elsewhere in the diagnostic. For example, with E0061:
```json
{
"message": "this function takes 2 parameters but 3 parameters were supplied",
"spans": [{"label": "expected 2 parameters"}]
}
```
However, with some mismatched type errors (E0308) the expected type only appears in the primary span's label, e.g.:
```json
{
"message": "mismatched types",
"spans": [{"label": "expected usize, found u32"}]
}
```
I initially added the primary span label to the message unconditionally. However, for most error types the child diagnostics repeat the primary span label with more detail. `rustc` also renders the duplicate text but because the span label and child diagnostics appear in visually distinct places it's not as confusing.
This takes a heuristic approach where it will only add the primary span label if there are no child message lines. For most error types the child messages repeat the primary span label with more detail.

This adds `unreachable_code` to the list of diagnostic codes we map to
`Unnecessary` in Visual Studio Code. This is consistent with what the
TypeScript language server does.
