[3006.x] Raise exception when bad pillar data is encountered

[dwoz]

What does this PR do?

RemotePillar raises an exception on bad data

If the master returns a bad pillar data response the pillar client
should raise an exception. This changes RemotePillar and
AsyncRemotePillar classes to use the same logic for validating pillar
data from the master. Fixes CVE-2024-37088 by causing salt-call to fail
with a non zero exit code rather than continuing to execute a state when
pillar data rendering fails on the master.
