Merge #4256

4256: Improve formatting of analyzer status text r=flodiebold a=eminence

The old formatting had everything on 1 line, making it quite hard to read:

    requests:    1 textDocument/documentSymbol         2ms    2 textDocument/codeAction             2ms    3 rust-analyzer/inlayHints            20ms    4 textDocument/foldingRange           108ms    6 textDocument/codeLens               66ms    5 textDocument/semanticTokens/range   76ms    8 rust-analyzer/inlayHints            195ms    7 textDocument/semanticTokens         250ms    9 textDocument/semanticTokens/range   108ms


It now looks like this:

```
requests:
*   1 textDocument/documentSymbol         11ms
    2 textDocument/codeAction             15ms
    3 rust-analyzer/inlayHints            4ms
    5 textDocument/foldingRange           3ms
    4 textDocument/semanticTokens/range   45ms
    6 textDocument/codeLens               182ms
    8 rust-analyzer/inlayHints            124ms
    7 textDocument/semanticTokens         127ms
    9 textDocument/documentHighlight      2ms
   10 textDocument/codeAction             3ms
```
