Max Wang 2618c50073 New runloop queue to coalesce Interface state update calls. (#788)
* fix SIMULATE_WEB_RESPONSE not imported #449

* Coalesce interface state updates to ASCATransactionQueue before CATransaction commit.

This will avoid duplicate interface state delegate calls caused by view repeatly added/removed to/from hierarchy during controller animation transition.

* fix tests for new run loop queue

* Support for disabling ASCATransactionQueue

* Fix didExitHierarchy to use ASCATransactionQueue.

* merge range managed and none range managed for didExitHierarchy

* Revert "merge range managed and none range managed for didExitHierarchy"

This reverts commit f807efaa65ed5dbdb6622d06da542e01a53715fa.

* merge range managed and none range managed for didExitHierarchy

* remove metadata

* abstract queue to impl class methods

* Add tests

* Fix test fail because of shared object.

* guard _pendingInterfaceState access with lock

* name refactor

* Refactor from comments https://github.com/TextureGroup/Texture/pull/788/\#pullrequestreview-94849919

* Apply InterfaceState immediately after ASCATranactionQueue is processed and before next runloop started.

* refactor

* no op to start CI build

* remove unused var and kick off tests

* change lisence

* remove code for weak ref

* add change log and adjust license
