Fix Unix issue with string address below 64kB (#7183)

This change fixes a problem that has started to occur in the ARM32 Linux CI
tests. A string located below 64KB in the address space is passed to the
StringObject::StringInitCharHelper and the code throws an exception since
on Windows, values below 64kB represent atoms and not strings.
This check should not be done for FEATURE_PAL though.
