Bug#1121238: apt not verify Packages* file hash if InRelease cache hit

When running `apt update`, if the InRelease file returns an IMS-Hit, the code will skip hash comparison directly, assuming all index files (including Packages) are up to date.

I believe that even when there is an InRelease Cache Hit, the local Packages file should still be verified for correctness (when incorrect, it may sometimes download packages that no longer exist, requiring manual cache clearing to resolve—parameters like `APT::Keep-Downloaded-Packages "false";` also do not take effect). Alternatively, an option could be provided to control whether Packages file verification is enabled (default enabled, and manually disabled when CPU saving is needed).

if (TransactionManager->IMSHit == true)

// Even with IMS-Hit, verify the hash value

if (TransactionManager->IMSHit == true && TransactionManager->LastMetaIndexParser != NULL)

// Hash comparison is still needed because InRelease might have been updated but returned an IMS-Hit

HashStringList const newFile = GetExpectedHashesFromFor(TransactionManager->MetaIndexParser, Target.MetaKey);

HashStringList const oldFile = GetExpectedHashesFromFor(TransactionManager->LastMetaIndexParser, Target.MetaKey);

if (newFile != oldFile)
