  Changed paths:
    M clang-tools-extra/clangd/ModulesBuilder.cpp

  Log Message:
  -----------
  [clangd] [C++20 Modules] Add --debug-modules-builder to not remove built module files on exit

In practice I found the option is very helpful for me to understand what
happens when clangd's C++20 modules support fails. With '--log=verbose',
I can rerun the command by clangd to understand what's going wrong
actually.

The documentation or adding the option to '--help' list can be done
separately.
