tracing/filters: Add filter_type to struct ftrace_event_field
The type of a field is stored as a string in @type, and here
we add @filter_type which is an enum value.
This prepares for later patches, so we can specifically assign
different @filter_type for the same @type.
For example normally a "char *" field is treated as a ptr,
but we may want it to be treated as a string when doing filting.
