perf(lsp): Cache semantic tokens for open documents (#23799) 
VScode will typically send a `textDocument/semanticTokens/full` request
followed by `textDocument/semanticTokens/range`, and occassionally
request semantic tokens even when we know nothing has changed. Semantic
tokens also get refreshed on each change. Computing semantic tokens is
relatively heavy in TSC, so we should avoid it as much as possible.

Caches the semantic tokens for open documents, to avoid making TSC do
unnecessary work. Results in a noticeable improvement in local
benchmarking

before:
```
Starting Deno benchmark
-> Start benchmarking lsp
   - Simple Startup/Shutdown 
      (10 runs, mean: 383ms)
   - Big Document/Several Edits 
      (5 runs, mean: 1079ms)
   - Find/Replace
      (10 runs, mean: 59ms)
   - Code Lens
      (10 runs, mean: 440ms)
   - deco-cx/apps Multiple Edits + Navigation
      (5 runs, mean: 9921ms)
<- End benchmarking lsp
```

chore: use rustfmt imports_granularity option (#17421) 
Closes https://github.com/denoland/deno/issues/2699
Closes https://github.com/denoland/deno/issues/2347

Uses unstable rustfmt features. Since dprint invokes `rustfmt` we do not
need to switch the cargo toolchain to nightly. Do we care about
formatting stability of our codebase across Rust versions? (I don't)
