efi_loader: update attribute check for QueryVariableInfo()

Current U-Boot supports two EFI variable service, U-Boot own
implementation and op-tee based StMM variable service.

With ACS Security Interface Extension(SIE) v22.10_SIE_REL1.1.0,
there are several failure items of QueryVariableInfo().

Current attribute check for QueryVariableInfo() was implemented
based on the Self Certification Test (SCT) II Case Specification,
June 2017, chapter 4.1.4 QueryVariableInfo().
This test case specification is outdated and don't align at all
with the SCT test case code, and UEFI specification v2.10 does
not clearly define the priority of the attribute check.

For U-Boot standard case that EFI variables are stored in a file
in the ESP, this commit modifies the attribute check to get align
to the EDK2 implementation.

For latter case(op-tee based StMM variable service), parameter check
should be delegated to StMM.

Now all ACS SIE QueryVariableInfo() test cases passed both EFI variable
storage implementations.
