MdeModulePkg/UefiBootManagerLib: API BmIsValidLoadOptionVariableName
Redfine the BmIsValidLoadOptionVariableName function to allow public use. Change name to EfiBootManagerIsValidLoadOptionVariableName to match naming scheme. Check that VariableName is never NULL and allow OptionType and OptionNumber to be optional.
