fix(ivy): i18n - correctly parse XLIFF placeholders (#34155) 

The ViewEngine translation extractor does not convert `-` to `_` for
placeholders that represent custom elements. For example `<app-component>`
gets converted to placeholders like `START_TAG_APP-COMPONENT`.

In `$localize` placeholders are expected to be snake-case, not kebab-case.
So we must normalize them when parsing a translation file that might have
been created via the View Engine translation extractor.

The `$localize` extraction code will normalize these placeholders when
creating translation files in the first place.

Fixes #34151

PR Close #34155
