/**
Find the first EFI_FORM_LABEL in FormSets for a given EFI_HII_HANLDE defined.
EFI_FORM_LABEL is a specific to Tiano implementation. The current implementation
does not restrict labels with same label value to be duplicated in either FormSet
scope or Form scope. This function will only locate the FIRST EFI_FORM_LABEL
with value as the same as the input Label in the Formset registered with UefiHiiHandle. The FormSet GUID
and Form ID is returned if such Label is found.
@param Handle Uefi Hii Handle to be searched.
@param Label The first Label ID to be found.
@param FormsetGuid The matched FormSet GUID.
@param FormId The matched Form ID.
@retval EFI_INVALID_PARAMETER If UefiHiiHandle is not a valid handle.
@retval EFI_NOT_FOUND The package list identified by UefiHiiHandle deos not contain FormSet or
Form ID with value Label found in all Form Sets in the pacakge list.
@retval EFI_SUCCESS The first found Form ID is returned in FormId.
