UEFI Settings from Template Not Inherited on VM Launch

### problem

A template was created with UEFI Secure Boot enabled, and its firmware setting is correctly configured as UEFI SECURE. However, when launching an instance from this template, the boot mode defaults to BIOS instead of inheriting the UEFI Secure setting from the template.

The boot mode need to be manually changed to UEFI Secure for every instance deployment.

### versions

CLOUDSTACK VERSION
4.22.1.0

HYPERVISOR
XCP-ng 8.3

### The steps to reproduce the bug

1.Create A template with UEFI Enabled and Update Settings

2. Lunch VM using Template
3. Boot Settings are Defaulted to BIOS

...

### What to do about it?

The deployment wizard default Boot Option should be chosen based on template settings.

Start by tracing the template settings through the VM deployment wizard for the XCP-ng path, comparing the saved UEFI Secure setting with the launch-time boot option. Reproduce with CloudStack 4.22.1.0 and XCP-ng 8.3, then verify that a VM launched from a UEFI-enabled template defaults to UEFI Secure rather than BIOS.
