Some fixes to make OMCC leaner

- Use inheritance for constants instead of passing them through each
  function.
- Use Modelica arrays (Integer yy_accept[:]) instead of MM arrays since
  Modelica arrays can be used as package constants.
- Move tokens, lexer tables, lexer code and lexer into the same file,
  inheriting from OMCCBaseLexer.mo.
