Allow to filter pages on hw type

Currently we patch out hardware specific pages downstream (e.g. https://salsa.debian.org/DebianOnMobile-team/phosh-tour/-/blob/debian/latest/debian/patches/debian/Disable-hw-specific-page.patch) to avoid them being shown on incompatible hardware. This isn't ideal as they're then also not shown on compatible hardware 😄

Filter pages by dt compatible instead.

Marking as draft as this is on top of !21 (merged) .
