Split GEMM instance library & enable pipeline v2 optimization (#783)

* Move source file into sub-directories

* Add missing include directive

* Split DeviceGemmXdl<> fp16 instances

* Fix format

* Remove unnecessary CMakeLists.txt

* Add macros to toggle new features

* Remove debug message

* Turn off GEMM v2 pipeline optimization by default

* Fix format

* Extract duplicated string as list

* Enlarge indent in CMakeLists.txt
