include[2/2]: move expect_eq_* test macros to include/wine/test.h

[Mikołaj Zalewski]

  Maybe we could have a common set of macros to test for equality, or is
this a bad idea? The macros uses the a naming convention
expect_eq_<printf format>[_<some option>] and evaluate the expression
only once, what makes it suitable to use a function call as the
expression. They are macros to preserve the line number in ok() calls.
