The magnitude already carries the sign of X direction. Having a signed
direction will inverse the effective direction. The Y and Z direction
sign and magnitude seem to be ignored.

Wine would append a correctly aligned NUL Unicode character to
terminate the string but overflow the buffer by one byte for odd-sized
strings.
Windows instead overwrites the last two buffer bytes with a NUL Unicode
character which ends up being misaligned for odd-sized strings.
The clipboard data has a size field anyway so match the Windows
behavior.
Tweak the tests to show that SetClipboardData() can overwrite half of
the Unicode string's last character.

A 0 or 1 byte Unicode string cannot be NUL terminated. That does stop
Windows 10 and older from doing so which is why the 1 byte test must be
skipped to avoid a crash in the 64-bit case.
But in such cases SetClipboardData() fails on Windows 11 and so should
Wine (instead of underflowing the buffer like Windows).
Reorganize the test data by increasing size.

Using wine_dbgstr_wn() causes out-of-bounds memory accesses when given
Unicode strings with odd sizes, most obviously 1 byte strings.
Also trace the expected Ansi string for round-trip tests.

This has the benefit of indicating why GetClipboardData() failed and of
matching the Windows 11 behavior.

Let conhost handle ctrl-\ instead of Unix tty, and pretend it's a
ctrl-pause/break key stroke.  This allows CUI application in processed
input mode not to close upon ctrl-\.

Note: this patch should be extended by adding insertion
of the CTRL_BREAK_EVENT into processes' crtl handler
(as it's done for CTRL_C_EVENT).
