Ajax: Simplify jQuery.ajaxSettings.xhr
Previously, jQuery.ajaxSettings.xhr, contents were wrapped in a try-catch
as we defined jQuery.support.ajax & jQuery.support.cors executed during the
jQuery load and we didn't want to crash if IE had native XHR disabled (which
is possible). While jQuery hasn't supported the ActiveX-based XHR since 2.0,
jQuery with XHR disabled could still be used for its other features in such
a crippled browser.
Since gh-4347, jQuery.support.ajax & jQuery.support.cors no longer exist, so
we don't need the try-catch anymore.
Fixes gh-1967
Closes gh-4467
Ref gh-4347
