BridgeJS: Add protocol-based intrinsic system

Introduce _BridgedSwiftTypeLoweredIntoSingleWasmCoreType protocol
to formalize lift/lower operations. All basic types (Bool, Int,
Float, Double) now conform to this protocol with standardized
bridgeJS* methods.

Add _BridgedSwiftHeapObject and _BridgedSwiftEnumNoPayload protocols
for heap objects and enums respectively.

Update generated code and test snapshots to use new protocol-based
intrinsic functions.
