refactor(ivy): ngcc - use a fixed set of properties to compile if none provided (#29092) 

Previously we always considered all the properties in the package.json
if no `propertiesToConsidere` were provided.
But this results in computing a new set of properties for each entry-point
plus iterating through many of the package.json properties that are
not related to bundle-format paths.

PR Close #29092
