5660367c77 Add clang.prependArgs option 
To specify arguments that are inserted immediately after the compiler
driver name. For example, initialization options
`{"clang":{"prependArgs":["--gcc-install-dir=/usr/lib/gcc/x86_64-linux-gnu/13"]}}`
transforms `clang -c a.cc` into `clang --gcc-install-dir=/usr/lib/gcc/x86_64-linux-gnu/13 -c a.cc`.
This allows users to provide default arguments that can be overridden as
needed.

Then build ccls against the just-built llvm-project.
```
cmake -S. -Bout/debug -G Ninja -DCMAKE_BUILD_TYPE=Debug -DCMAKE_CXX_COMPILER=$HOME/Stable/bin/clang++ -DCMAKE_EXPORT_COMPILE_COMMANDS=On -DCMAKE_PREFIX_PATH="$HOME/llvm/out/stable;$HOME/llvm/out/stable/tools/clang" -DCLANG_EXECUTABLE=$HOME/Stable/bin/clang++

Reformat all the files after 192a82b (#979) 
Since the introduction of "ColumnLimit: 120" in .clang-format, the
column limit has become 120 characters instead of 80 characters.

This prevents clang-format from generating too much changes even if just
a small portion of a source file or header file is modified.

664f952f38 Implement textDocument/switchSourceheader 
When the current file is X.cc, there might be multiple X.h.
Use a heuristic to find the best X.h.

Vote for each interesting symbol's definitions (for header) or
declarations (for non-header). Select the file with the most votes.

If `file_id2cnt` is empty, use a simpler heuristic.

cc13ced659 Support LSP semantic tokens 
This patch implements `textDocument/semanticTokens/{full,range}`. If the
client supports semantic tokens, $ccls/publishSemanticHighlight (now
deprecated) is disabled.

These token modifiers are mostly useful to emphasize certain symbols:
`static, classScope, globalScope, namespaceScope`.

To enable a colorful syntax highlighting scheme, set the
highlight.rainbow initialization option to 10.
https://maskray.me/blog/2024-10-20-ccls-and-lsp-semantic-tokens

Note that the older $ccls/publishSemanticHighlight protocol with
highlight.lsRanges==true (used by vscode-ccls) is no longer supported.
