fix(ivy): support for multiple ICU expressions in the same i18n block (#28083) 

There were two issues with multiple ICU expressions in the same i18n block:
- the regexp that was used to parse the text wasn't able to handle multiple ICU expressions, I've replaced it with parsing the text and searching for brackets (which is what we ended up doing in the end anyway)
- we allocate node indexes for nodes generated by the ICU expressions which increases the expando value, but we would create the nodes for those cases during the update phase. In the mean time we would create some nodes during the creation phase (comment nodes for ICU expressions, text nodes, ...) with an auto increment index. This means that any node created after an ICU expression would get the following index value, but the ICU case nodes expected to use the same index as well... There was a mismatch between the auto generated index, and the expected index which was causing problems when we needed to select those nodes for updates later on. To fix it, I've added the expected node index to the list of mutate codes that we generate, and we do not use an auto increment value anymore.
