fix(ivy): template compiler should render correct $localize placeholder names (#32509)

The `goog.getMsg()` function requires placeholder names to be camelCased.

This is not the case for `$localize`. Here placeholder names need
match what is serialized to translation files.

Specifically such placeholder names keep their casing but have all characters
that are not in `a-z`, `A-Z`, `0-9` and `_` converted to `_`.
