DSPTables: Deduplicate FindByOpcode() implementations in DSP opcode tables

This function was duplicated across all the opcode tables: the main info
tables, the interpreter tables, and the x86-64 JIT tables. However, we
can just make the type of the std::array parameter a template type and
get rid of this duplication.
