[trace] Add a flag to the decoder to output the instruction type

Browse Source 
To build complex binding upon instruction trace, additional metadata 'instruction type' is needed.

This diff has followings:
 - Add a flag -k  / --kind for instruction dump
 - Remove SetGranularity and SetIgnoreErros from Trace cursor

Sample output:

```
(lldb) thread trace dump instruction -k
