User should not be allowed to add template settings if the template has "Read Instance settings from OVA" enabled

### problem

User should not be allowed to add template setting if the template has "Read Instance settings from OVA" enabled

### versions

ACS 4.22

### The steps to reproduce the bug

1. Register a template in Cloudstack with "Read Instance settings from OVA"

2 Currently, the exception is only thrown, if the user tires to add a uefi setting

3. A similar exception message should be shown if the user tries to add the following settings

### What to do about it?

Do not allow the addition of template settings if the template has "Read Instance settings from OVA" enabled

首先追蹤現有的驗證邏輯：啟用 "Read Instance settings from OVA" 時，該邏輯會拒絕新增 UEFI 設定；接著找出 issue 中所示的其他範本設定在哪裡處理。對於受影響的範本，所有範本設定都會以類似的例外被拒絕，同時未受影響的範本仍然可以新增設定時，這項變更即完成。
