Improve shader profile extension to be more compatible with bgfx (#247)

* remove profile extension incompatible with those listed under examples/runtime/shaders; fix incorrect parameter names; enforce consistent syntax when appending to CLI.

* remove dx9

* add separate profile extension for paths vs profile extension
