Common jdk21u JBS labels

The above filters exclude issues that are marked with the following labels:

• jdk21u-na Change does not apply to open jdk21u. In general, this is a change done by Oracle for their build or test infrastructure, for their own delivery or in their tests not open sourced. Any other change might not be deemed appropriate for OpenJDK 21u and get labelled that way.
• jdk21u-defer-next Change is generally acceptable, but should go into the next JDK 21 update release. I.e. 21.0.4 is currently collecting fixes in jdk21u-dev, but the proposed change should get into 21.0.5 (the next release) instead.
