Adds JsInterop name collision checks.

Adds JsInteropRestrictionChecker (which works in both monolithic and 
incremental compiles) to perform general JsInterop validity checks. 
Initially checks and failure tests are provided for name collisions 
among field-field @JsExports, method-method @JsExports, method-field 
@JsExports, and method-field @JsTypes.

Additionally support is added specifically to allow @JsProperty method 
names (like x() and x(int x)) to collide and make sure that they're 
given mangled output names that don't collide. This behavior is also 
tested.
