Add offset and alignment immediates to ArrayLoad and ArrayStore AST nodes, text format, and binary encoding.

Multibyte array access operations in the WebAssembly GC spec reuse memarg immediates to specify a static byte offset and alignment hint. This adds support for parsing, printing, and binary reading/writing of these attributes for array load and store instructions.
