[chungquantin]

How to test the PR?

• Go to ./base-parachain or any parachain template.
• Run pop bench pallet --pallet=pallet_timestamp --extrinsic= (No runtime provided)

Changelog

• Add new method build_project to build any Rust projects with features and target, required for the tests of this PR. The method is shared with build_parachain.
• Add new method build_binary_path to locate the binary path of the provided Rust project. The method is shared with binary_path method.
• Implement new feature to automatically locate existing <runtime-name>.wasm to benchmark. The path of the runtime WASM blob follows:

./target/<PROFILE>/wbuild/<name-of-runtime>/<name_of_runtime>.wasm

• Add unit tests for new methods. To test the build_project method for the runtime, we build the mock project with wasm32-unknown-unknown as target and locates the .wasm file.
