Remove abseil dependency and update build scripts

Abseil has been removed from the dependency list in vcpkg.json and related CMake configuration. Patch handling for abseil and protobuf portfiles is now conditional on the target platform, improving compatibility with Emscripten. References to absl::log_internal_check_op have been removed from build targets.
