refactor: replace HBB env var with conan options

Replace HBB_RELEASE_BUILD environment variable with explicit Conan options
to decouple conanfile.py from specific build environments.

- Add 'with_wasmedge' and 'tool_requires_b2' options to conanfile.py
- Remove HBB_RELEASE_BUILD env var check from conanfile.py
- Pass options explicitly in build-core.sh: -o with_wasmedge=False -o tool_requires_b2=True
- Remove HBB_RELEASE_BUILD=1 export from build-full.sh
- Clean up HBB-specific commentary (already documented in release-builder.sh)
