Avoid compiler warning when casting the result of GetProcAddress()
...
It is most unfortunate that the return type of `GetProcAddress()` is
`FARPROC` (which is essentially `intptr_t(*)(void)): this type cannot
be cast by GCC without warnings to anything but the generic function
pointer type `void(*)(void)`.
Let's work around that.

Fix C++ signature of function mi_is_in_heap_region
...
Original code did not compile with MI_USE_CXX=ON as function
mi_is_in_heap_region was declared noexcept through macro mi_attr_noexcept
but defined without specification, i.e. implicitly with noexception(false)
Just adding the macro in the definition is enough to fix the issue
(tested with gcc 8.3.5)
