[TV app] Enable missing client callbacks

[lazarkov]

Problem

• TV example app does not have client callbacks needed for commissioning
• After callbacks were added, build failed because of unused variable kByteSpanSizeLengthInBytes = 2;

Change overview

• Updated tv.zap to include client callbacks
• Updated CHIPClientCallbacks-src.zapt and marked kByteSpanSizeLengthInBytes variable as maybe used
• Run zap_regen.sh to generate zzz_generated code

Testing

• Run the ./scripts/tests/test_suites.sh -a tv
