/**
set the value of an environment variable
This function changes the current value of the specified environment variable. If the
environment variable exists and the Value is an empty string, then the environment
variable is deleted. If the environment variable exists and the Value is not an empty
string, then the value of the environment variable is changed. If the environment
variable does not exist and the Value is an empty string, there is no action. If the
environment variable does not exist and the Value is a non-empty string, then the
environment variable is created and assigned the specified value.
This is not supported pre-UEFI Shell 2.0.
@param EnvKey The key name of the environment variable.
@param EnvVal The Value of the environment variable
@param Volatile Indicates whether the variable is non-volatile (FALSE) or volatile (TRUE).
@retval EFI_SUCCESS the operation was completed sucessfully
@retval EFI_UNSUPPORTED This operation is not allowed in pre UEFI 2.0 Shell environments
