Add the query "encryption_key_type" to OSInfo device type

:Release Notes:
Add the query "encryption_key_type" to OSInfo device type. It outputs
the result of calling nyx_os_info_query() for the
NYX_OS_INFO_ENCRYPTION_KEY_TYPE query.

:Detailed Notes:
- Replaces the now deprecated enumerant
  NYX_OS_INFO_MANUFACTURING_VERSION with its replacement
  NYX_OS_INFO_WEBOS_MANUFACTURING_VERSION.
- Set version to v1.1.0 .

:Testing Performed:
Verified that when nyx-modules was built with ENCRYPTION_KEY_TYPE
defined, the following command output the value of ENCRYPTION_KEY_TYPE:
  # nyx-cmd OSInfo query encryption_key_type
  develkey
and that when nyx-modules was built without ENCRYPTION_KEY_TYPE defined,
it returns an error:
  Error: Query not implemented

:Issues Addressed:
[ANG-9167] Add Nyx OS Info query for type of key used for signing
