Support OSC 110, 111, and 112 for resetting colors

This adds support for OSC 110, 111, and 112 escape sequences to reset
the foreground, background, and cursor colors in the terminal. The
changes include handling these sequences in the `strhandle` function of
`st.c`, allowing applications to reset colors to their default values.

The OSC sequences originated from Xterm control sequences and are now
widely used in terminal applications and supported by many terminal
emulators. For applications, this allows them to reset colors to
default values without needing to know the colors beforehand.

Similar to [dwm-flexipatch](https://github.com/bakkeby/dwm-flexipatch) this st 0.9.2 (f114bce, 2025-07-27) project has a different take on st patching. It uses preprocessor directives to decide whether or not to include a patch during build time. Essentially this means that this build, for better or worse, contains both the patched _and_ the original code. The aim being that you can select which patches to include and the build will contain that code and nothing more.

Essentially this means that this build, for better or worse, contains both the patched _and_ the original code. The aim being that you can select which patches to include and the build will contain that code and nothing more.
For example to include the `alpha` patch then you would only need to flip this setting from 0 to 1 in [patches.h](https://github.com/bakkeby/st-flexipatch/blob/master/patches.def.h):
