Pete Bacon Darwin c65ac7fbad perf(ivy): ngcc - exit early if the targeted package has been compiled (#29740)
Previously we always walked the whole folder tree looking for
entry-points before we tested whether a target package had been
processed already. This could take >10secs!

This commit does a quick check of the target package before doing
the full walk which brings down the execution time for ngcc in this
case dramatically.
