Add timeout checks in user32:cursorinfo

user32:cursorinfo sometimes fails Windows 10:

cursoricon.c:2444: Test failed: cursor not shown in info
cursoricon.c:2497: Test failed: cursor not shown in info
cursoricon.c:2509: Test failed: cursor not shown in info

See: https://test.winehq.org/data/tests/user32:cursoricon.html

This is not systematic. Only Windows 10 1809 is impacted so far, but this
affects both 32 and 64 bit tests and essentially all locales.

This test as some WaitForSingleObject() calls with 1s timeouts. So I used the
attached patch to check whether timeouts actually occur. Some do but after the
first of the above test failures.
