Adding the missing static sensor properties for the OV08X40 front camera
(0.7um OV08X, front cameras on Intel Meteor Lake laptops). Full report 
on the
now-working IPU6 + ov08x40 setup (kernel 7.2, libcamera, v4l2-compat shim in
Firefox/Zoom): https://gitlab.freedesktop.org/camera/libcamera/-/issues/237
Same change as branch ov08x40-properties in fork omikheev/libcamera,
commit 51a7a5c.

Subject: [PATCH] sensor: Add static properties for OV08X40

The OV08X40 9.2MP sensor (0.7um pixel, front-facing camera on
multiple Intel Meteor Lake laptop platforms) has no static sensor
properties, so libcamera falls back to generic defaults (including
an unverified unit cell size) for its AEC/AWB computation.

Add the unit cell size (700nm, per the OVT OV08X product spec) and
the test pattern modes matching the in-tree ov08x40 driver's
test_pattern control (0 = Off, 1 = Color Bars,
2 = Color Bars Fade To Gray).
