Prior to this commit, there was a property server.error.include-details
that allowed configuration of the message and errors attributes in a
server error response.

This commit separates the control of the message and errors attributes
into two separate properties named server.error.include-message and
server.error.include-binding-errors. When the message attribute is
excluded from a servlet response, the value is changed from a
hard-coded text value to an empty value.

Fixes gh-20505
