[PATCH] .gitignore: ignore compile_commands.json globally

[Andrii Nakryiko <andrii@kernel.org>]

compile_commands.json can be used with clangd to enable language server
protocol-based assistance. For kernel itself this can be built with
scripts/gen_compile_commands.py, but other projects (e.g., libbpf, or
BPF selftests) can benefit from their own compilation database file,
which can be generated successfully using external tools, like bear [0].

So, instead of adding compile_commands.json to .gitignore in respective
individual projects, let's just ignore it globally anywhere in Linux repo.
