Move exec out of pardes.zig into exec.zig

Pure move, no behaviour change (acme keeps this in exec.c): execute,
commandText, max_exec_depth, executeBuiltinLine, applyStartupConfig,
runBuiltin and applySettingBuiltin; the getarg-style operand code
(withArg, PointerOperand, pointerOperand, heldSelection, chordEachSel);
takesCommandLine and the terminals commands run in (spawnTty, spawnV9fsTty,
spawnTtyWithMount, evictLonePristineTty, replaceStillborn, ttyForDir);
placeDoc; and the save path (submitSave, saveFile, saveTo, askWrite), with
the acme-chords test, go verbatim to exec.zig.

The methods become free functions taking `p: *Pardes`. executeBuiltinLine
is called from ~170 places as `p.executeBuiltinLine(..)`, so Pardes keeps
one declaration alias for it and those call sites stay; the other 104 calls
change from `p.execute(..)` to `exec.execute(p, ..)`. ninep/ctl.zig has a
local named exec, so it writes `pardes.exec.execute` instead of importing
the file.
