Fix bgfx_compile_shaders section of README.md

* 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

 This defines a shaderc command to generate binaries or headers for a number of `TYPE` shaders with `SHADERS` files and `VARYING_DEF` file in the `OUTPUT_DIR` directory. There will be one generated shader for each supported rendering API on this current platform according to the `BGFX_EMBEDDED_SHADER` macro in `bgfx/embedded_shader.h` for headers and in the directory expected by `load_shader` in `bgfx_utils.h`.
