Problem:
Build is not reproducible, because generated source files (.c/.h/) are not
deterministic, mostly because Lua pairs() is unordered by design (for security).

Solution:
- Update the code generation scripts to be deterministic.
- That is only a partial solution: the exported function
(funcs_metadata.generated.h) and ui event
(ui_events_metadata.generated.h) metadata have some mpack'ed
tables, which are not serialized deterministically.
- As a workaround, introduce `PRG_GEN_LUA` cmake setting, so you can
inject a modified build of luajit (with LUAJIT_SECURITY_PRN=0)
that preserves table order.
- Longer-term we should change the mpack'ed data structure so it no
longer uses tables keyed by strings.

With #20374 tabline option is marked with 'statuslines' redraw flag.
But 'statuslines' doesn't redraw tabline. As a result, tabline doesn't
get redrawn when tabline option is set and statuslines get unnecessarily redrawn.
This patch fixes the issue by adding a new redraw flag P_RTABL to redraw
tabline.
This was used in the past with assumption that curwin/curbuf
is "special" but this has not been true since basically forever
at this point.
Reduce NOT_VALID/CLEAR panic in options.lua . These should not
be set if an effect of the option is causing something
which by itself invokes redraw_later().
Problem: Using expressions in a modeline is unsafe.
Solution: Disallow using expressions in a modeline, unless the
'modelineexpr' option is set. Update help, add more tests.

Problem: Cannot set 'dictionary' to a path.
Solution: Allow for slash and backslash. Add a test (partly by Daisuke
