do not allow crashes in isEmpty(int bx) method of BXVector [13_1_X]

[missirol]

backport of #41572

PR description:

From the description of #41572:

This PR aims to make the method BXVector::isEmpty(int bx) more robust, removing the possibility of runtime crashes when this method is called.

This public method can currently crash if the value of its bx argument is outside the range of valid BXs, or if the itrs_ class member is empty (as seen in the problematic events that led to the crashes fixed by #41466).

PR validation:

None beyond the checks done for #41572.

If this PR is a backport, please specify the original PR and why you need to backport that PR. If this PR will be backported, please specify to which release cycle the backport is meant for:

#41572

Fix to public method used by several plugins in CMSSW.

This pull request is fully signed and it will be integrated in one of the next CMSSW_13_1_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_13_2_X is complete. This pull request will now be reviewed by the release team before it's merged. @perrotta, @dpiparo, @rappoccio (and backports should be raised in the release meeting by the corresponding L2)
