gsi_util: add build.py to build and pack gsi_util
There are some command in build.py:
'setup_env' command can build the dependency files and copy these
files to the script.
'build' command also zip the dependency files to a zip file which
could be released independently.
The patch includes a list REQUIRED_ITEMS, which maintains the
source and destination of the dependency files. INCLUDE_FILES
maintains the files to be included to zip file additionally.
Uses 'list_deps' to list all dependency files.
Bug: 70253683
Test: setup_env and build command and check the files
