Does anyone know which file is the one which has the grammar in the Icarus Verilog compiler and also which one has the syntax error handing and printing?

I suppose that the grammar is the bison file https://github.com/steveicarus/iverilog/blob/master/vvp/parse.y (with the lexer in https://github.com/steveicarus/iverilog/blob/master/vvp/lexor.lex). You could start looking for error message handling in https://github.com/steveicarus/iverilog/blob/master/vvp/compile.cc.

Those are just guesses based on a couple of minutes looking at the repository. Good luck.
