Introduce unary and binary versions of the branch instruction. This will
give more ISA_OPC_BRANCH_XXX opcodes to work with. This helps to get rid
of these 'maybe' bitsets and is needed for the assembler.

In isaspec the displayname of a bitset defines what is shown in
dissassembly. The assembler only sees this representation and
needs to be able to handle it.

When there are active PMRs attached to the command buffer we can
not optimize the flush away, as that results in the queries never
reaching their expected sequence number, livelocking readers
waiting for the query result.

With libetnaviv_parser we are able to parse the resulting string
representation into an etna_inst and assemble that to binary.
As we are not able to parse and/or assemble we need to mark some test
cases with special flags.
This allows us to test: bin -> disasm -> parsing -> assemble
If isa_parse_str(..) is not available we skip this part of the unit
test.

This commit adds the actual parser, which makes use of the IsaParser
derive proc macro.
It provides two public functions:
- asm_process_str(..)
Parse the provided isa representation and return an etna_asm_result.
This will be used by our unit tests.
- asm_process_file(..)
Parse a whole file full of isa and return an etna_asm_result. This
will be used by our cli assembler.

This proc derive macro does the following magic:
- read static rules file
- parse isaspec xml file
- generate valid pest PEG grammar and attaches it as grammar_inline to
the ast
- calls pest_generator::derive_parser(..) to generate the parser
- creates FromPestRule trait
- creates FromPestRule impl for enums and opcodes
