[CI] Change cache cleanup threshold from 1/2 to 1/3 

Sometimes cache sizes for Windows CI builds on main branch are smaller
compared to caches from other branches for unknown reasons. In that case,
a cache from a successful build could be accidentally removed when using
the 1/2 threshold. This commit reduces the threshold to 1/3 to be more
conservative and preserve successful build caches.

DESCRIPTION:
This script uses a dynamic size threshold of 1/2 of maximum cache size
This script uses a dynamic size threshold of 1/3 of maximum cache size
as the cleanup threshold. It employs regex pattern matching to find caches
with '.*PATTERN.*' for flexible matching. The system keeps the top 1 cache
to preserve the most recent successful build.
