This PR fixes a regression introduced in https://github.com/ethereum/go-ethereum/pull/33836/changes

Before PR 33836, running mainnet would automatically bump the cache size
to 4GB and trigger a cache re-calculation, specifically setting the key-value 
database cache to 2GB.
 
After PR 33836, this logic was removed, and the cache value is no longer
recomputed if no command line flags are specified. The default key-value 
database cache is 512MB.

This PR bumps the default key-value database cache size alongside the
default cache size for other components (such as snapshot) accordingly.
