beam_asm: Simplify string table generation for beams
The code for generating the string table (which is now only used for bit syntax matching) in a BEAM file is quite complicated and potentially expensive when compiling modules with many thousands of clauses doing bit syntax matching. Simplify and optimize the code using bit syntax and binary:match/2 instead of the list operations in the original code.
