refactor(avm): avm memory trace building (AztecProtocol#3835)

Resolves AztecProtocol#3834 

Moving all AVM memory related trace building functions into a dedicated
class.
Furthermore, all AVM related trace files were moved into a dedicated
folder in vm.
The following files:

- AvmMini_common.hpp
- AvmMini_helper.cpp
- AvmMini_helper.hpp
- AvmMini_mem_trace.cpp
- AvmMini_mem_trace.hpp
- AvmMini_trace.cpp
- AvmMini_trace.hpp
were moved from 

barretenberg/cpp/src/barretenberg/proof_system/circuit_builder/

to

barretenberg/cpp/src/barretenberg/vm/avm_trace/

Finally, the namespace for these files were migrating from proof_system
to avm_trace.
