ext: handle diaseembler initialization from --extension
There are two options to specify custom extension and register it
1. --isa with x ex: --isa=rv64gcv_xmyext
parse, load, register in processor_t::processor_t
2. --extension
parse, load in main
register later by calling processort_t::register_extension
The patch fix the register pass in 2
