✅ Add XCM Transact emulator tests

[dastansam]

This pull request introduces several changes to the integration tests and runtime configurations, primarily focused on replacing rococo-runtime with westend-runtime and adding support for the AssetHubWestend parachain. The changes include updates to dependencies, constants, runtime configurations, and the addition of new test cases for cross-chain transactions.

Key Changes:

Transition from rococo-runtime to westend-runtime:

• Updated dependencies in Cargo.toml files to replace rococo-runtime and rococo-runtime-constants with westend-runtime and westend-runtime-constants (Cargo.toml, integration-tests/Cargo.toml). [1] [2] [3] [4] [5]
• Updated runtime constants and session keys in integration-tests/src/constants.rs to use westend-runtime equivalents. [1] [2] [3]

Addition of AssetHubWestend support:

• Introduced a new module asset_hub in integration-tests/src/constants.rs to define the genesis configuration and constants for AssetHubWestend.
• Declared the AssetHubWestend parachain in integration-tests/src/lib.rs, including its runtime, core, and pallets. Helper macros for accounts, assets, and XCM were also implemented.
• Added AssetHubWestend to the test network (PolkadotNet) and updated shortcuts for runtime types to include AssetHubWestend. [1] [2]

New XCM transaction test:

• Added a new test module transact.rs to validate Cross-Consensus Messaging (XCM) between AssetHubWestend and Polimec. The test ensures that a Polimec Remark call can be successfully sent from AssetHubWestend to Polimec.

Miscellaneous updates:

• Updated integration-tests/src/lib.rs to include the new asset_hub module and helper imports.
• Enabled the new transact test module in integration-tests/src/tests/mod.rs.

These changes collectively enhance the integration test framework by introducing support for the westend-runtime and extending the test coverage to include the AssetHubWestend parachain.
