Improve spirv-fuzz CMake code (#3781)

This change improves spirv-fuzz CMake code to be more compatible with other projects that might want to include spirv-fuzz as a sub-project.

* Add a CMake option for building spirv-fuzz. 
* We now check if protobuf targets are already available. 
* We no longer specify `-DGOOGLE_PROTOBUF_NO_RTTI -DGOOGLE_PROTOBUF_USE_UNALIGNED=0`; a newer version of protobuf does not require this. Note that we probably should have specified this for protobuf targets as well, but this is no longer needed. 
* Updated protobuf version in Kokoro scripts and README.md.
