Add support for background blur

This patch adds a new config option: colors{,2}.blur=no|yes. When
enabled, transparent background are also blurred.

Note that this requires the brand new ext-background-effect-v1
protocol, and specifically, that the compositor implements the blur
effect.

* `[colors-light]` section to `foot.ini`. Replaces `[colors2]`.
* `XTGETTCAP`: added `query-os-name`, returning the OS foot is
compiled for (e.g. _'Linux'_) ([#2209][2209]).
* Preliminary (untested) support for background blur via the new
`ext-background-effect-v1` protocol. Enable by setting
`colors-{dark,light}.blur=yes`. Foot needs to have been **built**
against `wayland-protocols >= 1.45`, and the compositor **must**
implement the `ext-background-effect-v1` protocol, **and** the
`blur` effect.
