Olivier Combe 00cc905b98 feat(ivy): support ng-content in runtime i18n translations (#30782) 
Added a new syntax for projections (`¤` will represent `ng-content` nodes) so that we can treat them specifically.
When we enter an i18n block with the instruction `i18nStart`, a new `delayProjection` variable is set to true to prevent the instruction `projection` from projecting the nodes. Once we reach the `i18nEnd` instruction and encounter a projection in the translation we will project its nodes.
If a projection was removed from a translation, then its nodes won't be projected at all.
The variable `delayProjection` is restored to `false` at the end of `i18nEnd` so that it doesn't stop projections outside of i18n blocks.
