(API Change) libobs: Pass type data to get_name callbacks

API changed from:
obs_source_info::get_name(void)
obs_output_info::get_name(void)
obs_encoder_info::get_name(void)
obs_service_info::get_name(void)

API changed to:
obs_source_info::get_name(void *type_data)
obs_output_info::get_name(void *type_data)
obs_encoder_info::get_name(void *type_data)
obs_service_info::get_name(void *type_data)

This allows the type data to be used when getting the name of the
object (useful for plugin wrappers primarily).

NOTE: Though a parameter was added, this is backward-compatible with
older plugins due to calling convention.  The new parameter will simply
be ignored by older plugins, and the stack (if used) will be cleaned up
by the caller.
