hw/block/nvme: Add Commands Supported and Effects log

Browse source 
This log page becomes necessary to implement to allow checking for
Zone Append command support in Zoned Namespace Command Set.

This commit adds the code to report this log page for NVM Command
Set only. The parts that are specific to zoned operation will be
added later in the series.

All incoming admin and i/o commands are now only processed if their
corresponding support bits are set in this log. This provides an
easy way to control what commands to support and what not to
depending on set CC.CSS.
