etnaviv: isa: Add meta elements to instructions

Browse source 
This commits adds a meta elements with the following attributes:
- has_dest: does the instruction has a dest register?

- valid_srcs: which sources need to be valid?
  Is used to generate PEST grammar and defines which of the three source
  registers needs to be != void.

- type: which <template> shall be used?
  Must match a known template name by the last part.
  E.g.: <meta type=tex"/> --> <template name="INSTR_TEX">
