Title: Debug TZInfo zones in time_zone_options_for_select

Fixes issue #7245

time_zone_options_for_select only generates option tags for Rails zone
identifiers. TZInfo identifiers were getting ignored invisibly, if passed as
the +selected+ arg.

This change generates option tags for all identifiers recognized
by ActiveSupport::TimeZone, so TZInfo identifiers can be preselected too.
