ToolUtils: Add helper to compile shader to header

Remove unused add_shader and shaderc
Example usage:
```
shaderc_parse(
  CLI
  ${ARGS_TYPE} ${PLATFORM_I} WERROR
  "$<$<CONFIG:debug>:DEBUG>$<$<CONFIG:relwithdebinfo>:DEBUG>"
  FILE ${SHADER_FILE_ABSOLUTE}
  OUTPUT ${OUTPUT}
  PROFILE ${PROFILE}
  O "$<$<CONFIG:debug>:0>$<$<CONFIG:release>:3>$<$<CONFIG:relwithdebinfo>:3>$<$<CONFIG:minsizerel>:3>"
  VARYINGDEF ${ARGS_VARYING_DEF}
  INCLUDES ${BGFX_SHADER_INCLUDE_PATH}
  BIN2C BIN2C ${SHADER_FILE_NAME_WE}_${PROFILE_EXT}
)
```
