Use @lldb.command Decorator for LLDB Script Loading

[p-x9]

Currently, custom commands defined in python are registered by calling command script add.

However, the lldb framework provides a decorator to load custom commands.
It is simpler to use this to write.

Current

def __lldb_init_module(debugger: lldb.SBDebugger, internal_dict: dict) -> None:
    debugger.HandleCommand('command script add -f xxx.my_custom_command yyy -h "DESCRIPTION"')

def my_custom_command(debugger, command, result, internal_dict):
    # Implementation of the custom LLDB command here

↓↓↓↓↓↓

New

@lldb.command('yyy', doc='DESCRIPTION')
def my_custom_command(debugger, command, result, internal_dict):
    # Implementation of the custom LLDB command here

[p-x9]

From now on, we will define custom commands based on lldbhelper.LLDBCommandBase.

For simple commands, I suggest using @lldb.command decorator to define them.
