Subject: [PATCH] Check permissions for CDM shell commands
Override handleShellCommand instead of onShellCommand because
Binder.onShellCommand checks the necessary permissions of the caller.
Bug: 313428840
Test: manually tested CDM shell commands
(cherry picked from commit 1761a0fee9c2cd9787bbb7fbdbe30b4c2b03396e)
