Add tests to proposed new builtin async_copy functions with a bug fix. (#725)
* Add tests to proposed new builtin async_copy functions with a bug fix.
* Revert "Add tests to proposed new builtin async_copy functions with a bug fix."
This reverts commit 7d0f16d014.
* Add tests to proposed new builtin async_copy functions.
* Added is_extension_available to check if an extension is available.
* Added is extension available for test_async_copy_fence.
* fix build issues on windows.
* include algorithms.h for async copy 2D/3D.
* adding algorithms header.
* Fix numLines - 1 in maxTotalPlanesIn/Out.
* fix formatting violations.
* fixed formatting issue.
