Fix access flags passed to getFieldInfo in interpreter (#122009)

The interpreter compiler incorrectly passes CORINFO_ACCESS_GET to the
getFieldInfo for CEE_STSFLD and CEE_STFLD opcodes. That causes failure
in one of the libraries tests that initializes
BitConverter.IsLittleEndian field.

This change puts in the correct CORINFO_ACCESS_SET flag.
