This feature is useful for 3rd-party software to run GDB with predefined options that described in project_description.json file allow to pass custom options to "idf.py gdb": --gdb-commands: command line arguments for gdb. (without changes) -ex: pass command to gdb. -x: pass gdbinit file to gdb. Alias for old --gdbinit command

# General Workflow:
|
|
# 1. read all components dirs, a semicolon-separated string (cmake list)
|
|
# 2. map the component dir with a unique prefix /COMPONENT_<NAME>_DIR
|
|
# 2. write the prefix mapping file to $BUILD_DIR/prefix_map_gdbinit
|
|
# 3. print the unique prefix out, a space-separated string, will be used by the build system to add compile options.
