This patch adds FeatureSVEB16B16 to represent the new behavior of FEAT_SVE_B16B16 as described in the latest 
[Armv9.4 extensions documentation](https://developer.arm.com/documentation/109697/0100/Feature-descriptions/The-Armv9-4-architecture-extension?lang=en#md461-the-armv94-architecture-extension__FEAT_SVE_B16B16), as well as a 'sve-b16b16' flag to enable it. The predication of SVE BFloat16 to BFloat16 instructions has changed to reflect the new behavior of FEAT_SVE_B16B16. This change weakens the existing 'b16b16' flag used to enable the old version of FEAT_SVE_B16B16; it is partially replaced by the new 'sve-b16b16' flag. Existing tests that are effected by this have been modified to use and/or expect 'sve-b16b16', and new tests have been added to verify the behavior and implementation of 'sve-b16b16'. 

This patch is in response to the response to the following changes.

The architecture features previously enabled by FEAT_SVE_B16B16 have been relaxed such that it now implements:
      - With FEAT_SVE2 : SVE non-widening BFloat16 instructions in Non-streaming SVE mode
      - With FEAT_SME2: SVE non-widening BFloat16 instructions when the PE is in Streaming SVE mode and SVE
        Z-targeting multi-vector non-widening BFloat16 instructions.
      - **It no longer implements** SME ZA-targeting non-widening BFloat16 instructions.      

The SME ZA-targeting non-widening BFloat16 instructions are implemented by the new FEAT_SME_B16B16, **this patch does not change how this architecture feature is enabled** ('+b16b16+sme2'). Only those that are implemented by FEAT_SVE_B16B16 have been changed to require 'sve-b16b16' instead of 'b16b16'.

New flags must be created to represent FEAT_SVE_B16B16 and FEAT_SME_B16B16:
      - 'sve-b16b16' enables the updated FEAT_SVE_B16B16 (described here)
      - 'sme-b16b16' will enable the new FEAT_SME_B16B16
      - **This patch includes only 'sve-b16b16'**
   
A future patch will add 'sme-b16b16', SME ZA-targeting non-widening BFloat16 instructions would then be guarded by '+sme-b16b16+sme2', and 'b16b16' can be removed.
