Bug description:
[Impact]
No on-screen keyboard in gdm and can't enter password if there is no keyboard is connected.

[Fix]
Added those tablets to dmi_vgbs_allow_list() to read tablet mode while probing fixes the issue.
https://lkml.org/lkml/2025/11/27/285

Included in v6.19-rc1
b169e1733cadb platform/x86/intel/hid: Add Dell Pro Rugged 10/12 tablet to VGBS DMI quirks

[Test]
Boot up the affected tablets to gdm without touching any physical keys, the on-screen keyboard should pop up.

[Where problems could occur]
Current BIOS is reliablely to report the tablet mode during probing intel hid driver, but when it fails, it may report the wrong state and show the on-screen keyboard when keyboard is connected.
