[PATCH v4 1/1] qapi: Restrict code generated for user-mode

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

A lot of QAPI generated code is never used by user-mode.

Split out qapi_system_modules and qapi_system_or_tools_modules
from the qapi_all_modules array. We now have 4 groups:
- always used
- only used by system-mode
- not used by user-mode
- not used by tools
