[vulkan] Remove deep copies, fix issues in codegen.py

Not needed; now android/scripts/generate-vulkan-sources.sh
is much faster.

Abort on error in generating expression in codegen to sidestep
pylint issue.

Also, add ability to increment indent in CodeGen without having to
specify blocks explicitly.
