Matan Lurey eb42dc7b9d Add and use mergeGnArgs with --gn-args from et. (flutter/engine#56228)
Closes https://github.com/flutter/flutter/issues/156909.

This PR adds (and implements) the `--gn-args` (extra command-line GN args) functionality by generalizing on the concept of "merged" GN args that @zanderso had special-cased for `--lto` and `--rbe`, and further testing it.

There is also a logical place for us to expand support of merged arguments at a future point in time.
