Original description:
On Windows, the `ScrollConsoleScreenBufferW` function is being looked like this:
https://github.com/openjdk/jdk/blob/a253e0ff4b88541d01596b0e73ede4b96a258fca/src/jdk.internal.le/share/classes/jdk/internal/org/jline/terminal/impl/ffm/Kernel32.java#L406
I.e. the parameters are `MemorySegment`s/pointers. But, it is being invoked like this:
https://github.com/openjdk/jdk/blob/a253e0ff4b88541d01596b0e73ede4b96a258fca/src/jdk.internal.le/share/classes/jdk/internal/org/jline/terminal/impl/ffm/Kernel32.java#L239
I.e. with values rather than with pointers. This then fails at runtime when the function is called with an exception like:

Caused by: java.lang.invoke.WrongMethodTypeException: handle's method type (MemorySegment,MemorySegment,MemorySegment,MemorySegment,MemorySegment)int but found (MemorySegment,SMALL_RECT,SMALL_RECT,COORD,CHAR_INFO)int
        at java.base/java.lang.invoke.Invokers.newWrongMethodTypeException(Invokers.java:521)
        at java.base/java.lang.invoke.Invokers.checkExactType(Invokers.java:530)
        at jdk.internal.le/jdk.internal.org.jline.terminal.impl.ffm.Kernel32.ScrollConsoleScreenBuffer(Kernel32.java:239)


The proposal here is to use MemorySegments embedded in the provided parameters. This is consistent with the rest of the file, see for example here:
https://github.com/openjdk/jdk/blob/a253e0ff4b88541d01596b0e73ede4b96a258fca/src/jdk.internal.le/share/classes/jdk/internal/org/jline/terminal/impl/ffm/Kernel32.java#L173
