[0.4.14][NTUSER] Allow Window Snap to be disabled and optimize

Browse source 
Win+Left, Win+Right, Win+Up, and Win+Down can be disabled by registry value WindowArrangementActive REG_SZ 0 in
HKEY_CURRENT_USER\Control Panel\Desktop
Snapping mouse can be also disabled.

by porting back:
0.4.15-dev-5703-g d04e148d1c Optimize window snap disabling (#5061)
0.4.15-dev-5641-g ea55101aad Allow Window Snap to be disabled (#5014) CORE-16379 (#5014)

Also port back some minor unrelated improvements:
0.4.15-dev-3341-g 4bc95812fd defwnd.c Mark default as unreachable.
0.4.15-dev-316-g 938df97b54 nonclient.c NC_IconForWindow(): Remove redundant if() (#2842)
and:
-defwnd.c: delete a malformed TRACE() which had a format string, but no argument.
