hwdb: mark Microsoft Surface Type Cover touchpad as internal (#43262)

The Microsoft Surface Type Cover touchpad (USB 045E:09C0) is attached
through a USB port that firmware reports as removable. Because of that,
`65-integration.rules` sets `ID_INPUT_TOUCHPAD_INTEGRATION=external`,
and libinput skips disable-while-typing (DWT) for the device.

The touchpad is physically integrated into the Type Cover, so add a hwdb
entry in `70-touchpad.hwdb` that overrides
`ID_INPUT_TOUCHPAD_INTEGRATION=internal`, restoring DWT.

Fixes #43256
