Remove the low-end GPU mode from the settings.

Browse Source 
The user asked for it: the mode no longer gains frame rate, and the mesh shader fallback covers the cards it was written for. Its switch in the settings menu's Game tab is gone with the rows under it, and so are their 57 text ids and strings.

low_end_gpu itself does nothing any more. It is still a known key, so an older nx2navi.ini gives no unknown-key warning, and while it is on the log says once that the mode was removed in 0.10.2. The preset that gave nine keys other defaults is gone, and so is the rule that read the mode's keys only while it was on: each of them (mesh_emulation, tex_clobber, foliage, vram_heap_limit, vram_reserve_mb, upload_batch_mb, mirror_stage, mirror_hot, submit_finish_gpu and the others) is an ordinary setting with the default of its row or of its reader, so a line a player wrote by hand keeps counting and a file with only the switch runs the game as it runs for everyone else. guest_opt in nx2navi.ini counts for the next rebuild without the switch too (tools/make_game.py).

The recorder thread read the switch itself: on an AMD card without mesh shaders the mode turned it on. It is off on every AMD card now unless vk_recorder = 1 is set.

nx2navi.ini.example lists the former mode's settings as single settings, the 0.10.2 notes have a Removed entry and name the foliage fix of the commit before this one, and the comments that said what the mode sets say so in the past tense. tests/cfg_parse_check has the new reading of the switch and of the keys without it; the test matrix is at 90 ok with the same two not ok as before (installer_test, worktree_test), and a clean build compiles 169 runtime files and links. Not run in the game.

`cfg_bool`, `check_value`) passes `python tests\cfg_parse_check.py`, which builds `cfg.c` with stand-ins for what it
links with and loads scratch files: a comment after a value of a setting with a set of values is cut and logged once
with its line, free text, a value in double quotes and the environment keep theirs; switches written as words read as
0 or 1 through every reader, the low-end mode's switch (`lowend_of`, read apart from `cfg_get`) included; values
0 or 1 through every reader; `low_end_gpu`, the switch of the low-end GPU mode that 0.10.2 removed, turns nothing on
and is named once in the log (`lowend_set`), and the mode's keys are read by themselves; values
outside their sets are logged with their line, at most 16 lines and a count; a full settings table logs one line at
load and one for the menu. The launcher's reader (`launcher/gameini.py`) has the same comment lines in
`tests\launcher_test.py` `PlayerIniTest`, and `tools/make_game.py`'s own reads of `shader_carry` and `low_end_gpu`
`tests\launcher_test.py` `PlayerIniTest`, and `tools/make_game.py`'s own reads of `shader_carry` and `guest_opt`
(`shader_carry`, `guest_opt_ini`) theirs in `MakeGameTest`. No game files.
