Export local types (enums, structs) with dumpinfo

Describe the solution you'd like
I'm willing to write the code for it. I'd like to add a new section to the json, like so:

"local_types": {
    "structs": [
    	{
    		"name": "CPed",
    		"name_demangled": "CPed",
    		"size": 128,
    		"members": [
				{
					"type": "ePedType",
					"name": "m_nPedType",
					"offset": 4,
				}
    		]
    	}
    ],
    "enums": [
    	{
    		"name": "ePedType",
    		"name_demangled": "ePedType",
    		"values": [
    			["PED_TYPE_PLAYER", 1]
    		]
    	}
    ]
}

Describe alternatives you've considered
I do have another tool to do this job, but I'd rather have it here.

Are you okay with it?
Just asking, cause I don't want to spend time on something that wont get merged.

Looks OK (in any way I think it will be changed during implementation)
