Add the ability to use compile_commands.json for clang-tidy

I have really weird build system, that generates huge commandline for each file. As far as I understand OS simply can't handle so long command line, and I get following error

16:55:31: Running Clang-Tidy on D:\CMakeLists.txt with configuration "Almost everything(no Clazy)".
Analyzing "D:\foo.cpp" [Clang-Tidy].
Failed to analyze "D:\foo.cpp": An error occurred with the Clang-Tidy process.
Command line: <683575 chars long command line>
Process Error: 0
Output:
16:55:31: Error: Failed to analyze 1 files.
16:55:31: Clang-Tidy finished: Processed 0 files successfully, 1 failed.
16:55:31: Elapsed time: 00:00.

clangd, in turn, works just fine. I assume, that is so, because it uses compile_commands.json. If I take clang-tidy's command line and simply replace all compiler flags with

-p C:\Users\me\AppData\Roaming\QtProject\qtcreator\.qtc_clangd\default\

it works just fine. I wanted to rebuild clangtools and hardcode the falg here , but I'm not smart enough to do it on my own.

Maybe somabody can add setting "Use custom compile_commands.json", or even "Use clangd's compile_commands.json"?
