CreatePatchLibrary is broken

Description

It seems the FEditorShaderCodeArchive.LoadExistingShaderCodeLibrary missed some functions, use FEditorShaderCodeArchive.AddShaderCodeLibraryFromDirectory instead could fix the issue.

Steps to Reproduce
  1. Package a project, back up the folder "Saved\Cooked[Platform_ShaderFormat][ProjectName]\Metadata"
  2. Modify a material, package the project again.
  3. Run commandlet ./UnrealEditor.exe -run=ShaderCodeLibraryTools "Prev MetaData Path" "New MetaData Path" "OutputPath"

It crashed at the following place.
