Describe the bug
The refactored LLCP is using the legacy ctrl Tx buffers, which it should not use. This results in using too much RAM
See PR #49326 for reproducing the issue

Expected behavior
The ctrl Tx buffers should be removed without having an effect on the new LLCP

Impact
Not all features can be enabled when running on the nRF5340 due to RAM usage
