Merge branch '2023-10-11-port-gen_compile_commands_py'

To quote the author:
I'm submitting a patch series that ports the gen_compile_commands.py
script from the Linux kernel's sources to U-Boot. This script,
originally located in scripts/clang-tools/gen_compile_commands.py,
enables the generation of compile_commands.json file for improved code
navigation and analysis. The series consists of the initial script
import, the necessary modifications for U-Boot compatibility, and
finally some documentation.
