Update heterogeneous-hello-world to use gfx changes + delete shader.cpp (#2085)

* Update heterogeneous-hello-world to use gfx changes + delete shader.cpp

* Remove "experimental feature" tag from premake

* Add placeholder executeComputation_0() to shader.cpp

* Add shader.cpp to heterogeneous-hello-world files in premake

* Added project "heterogeneous-first-gen" to address first time build issues

* Re-add "experimental feature" tag, clean up generated file structure
