/*
  This function allows platform to refresh all boot options specific to the platform. Within
  this function, platform can make modifications to the auto enumerated platform boot options
  as well as NV boot options.

  @param[in const] BootOptions             An array of auto enumerated platform boot options.
                                           This array will be freed by caller upon successful
                                           exit of this function and output array would be used.

  @param[in const] BootOptionsCount        The number of elements in BootOptions.

  @param[out]      UpdatedBootOptions      An array of boot options that have been customized
                                           for the platform on top of input boot options. This
                                           array would be allocated by REFRESH_ALL_BOOT_OPTIONS
                                           and would be freed by caller after consuming it.

  @param[out]      UpdatedBootOptionsCount The number of elements in UpdatedBootOptions.


  @retval EFI_SUCCESS                      Platform refresh to input BootOptions and
                                           BootCount have been done.

  @retval EFI_OUT_OF_RESOURCES             Memory allocation failed.

  @retval EFI_INVALID_PARAMETER            Input is not correct.

  @retval EFI_UNSUPPORTED                  Platform specific overrides are not supported.
