Add a setting to force LTR / logical order for incoming text

# Description of the new feature/enhancement

Created out of: #12294
For reference: https://sw.kovidgoyal.net/kitty/conf/#opt-kitty.force_ltr

The following applies practically only to Hebrew:
Some applications (`vim -H` for instance) write RTL scripts already in reverse in order to place glyphs on the right side of the terminal. In order for us to support such RTL-aware applications we need to add a setting which allows the user to suppress BiDi detection.

# Proposed technical implementation details (optional)

When we add BiDi detecting in AtlasEngine, we should skip the detection if rendering in "logical order" is force-enabled.

Review issue #12294 and the AtlasEngine BiDi-detection work first, then compare the referenced kitty force_ltr behavior. The setting is done when users can force logical order so BiDi detection is skipped, preserving text from RTL-aware applications such as vim -H.
