CodeChecker doesn't support relative compiler paths

[Discookie]

Describe the bug
Having relative ../ compilers in the commands of the compilation database cannot be parsed by CodeChecker.

[ERROR 2024-09-08 20:59] - Failed to get and parse version of: ../../third_party/llvm-build/Release+Asserts/bin/clang++
[ERROR 2024-09-08 20:59] - [Errno 2] No such file or directory: '../../third_party/llvm-build/Release+Asserts/bin/clang++'

Ericsson/CodecheckerVSCodePlugin#155

CodeChecker version
6.24.0

To Reproduce
The Chromium repository's generate_compdb.py generates some entries like this.

Additional context
Example compdb entry:

  {
    "directory": "/[...]/src/out/frame_debug_apollo_arm64",
    "command": "../../third_party/llvm-build/Release+Asserts/bin/clang++ -MMD -MF obj/chrome/updater/base/setup.o.d [...]",
    "file": "../../chrome/updater/mac/setup/setup.mm",
    "output": "obj/chrome/updater/base/setup.o"
  },
