EEx.compile_string/2 was passing all options to tokenize/2, but
tokenize/2 only accepts tokenize_opt (:file, :line, :column,
:indentation, :trim). This caused dialyzer to correctly flag calls
with :engine or :parser_options as type errors in Elixir 1.19+.
The fix filters options before passing to tokenize/2, keeping only
the valid tokenize_opt keys, while still passing the full options
list to EEx.Compiler.compile/3 which needs :engine, :parser_options,
and custom engine options.
Fixes#14834
