mention that caller() does not show XSUBs

Part of Perl #113438. Someone may write a pure perl sub, or callback from
an XSUB to PP to use caller, to check the package of the sub that called
the current sub and have different behaviour based on the caller sub's
package. Also using a perl debugger will not show XSUB frames in the
call stack. Therefore document this limitation of caller.
