tplink-safeloader: add TL-WPA8635P v3

Inspecting the only available firmware
wpa8635pv3_fr-up-ver3-0-0-P1-20210625-rel39993-APPLC.bin shows the
WPA8631Pv3 EU is also supported by that firmware and the partition
layout is identical to the currently supported WPA8631P v3 layout.

Expand size of support-list partition into unused space in soft-version
(which is also supplied by tplink-safeloader) to fit the new entry.
