fix(ivy): i18n - support colons in $localize metadata (#32867)

Browse Source 
Metadata blocks are delimited by colons. Previously the code naively just
looked for the next colon in the string as the end marker.

This commit supports escaping colons within the metadata content.
The Angular compiler has been updated to add escaping as required.
