Wire: Implement MapWriteAsync

The flow of commands is a bit more involved than for MapReadAsync and
goes like this:
 - C->S MapAsync isWrite = true
 - S: Call MapWriteAsync
 - S: MapWriteAsync callback fired
 - S->C: MapWriteAsyncCallback (no data compared to the read case)
 - C: Call the MapWriteAsync callback with a zeroed out buffer
 - C: Application calls unmap.
 - C->S: UpdateMappedData with the content of the mapped pointer
 - S: Copy the data in the mapped pointer
 - C->S: Regular unmap command
 - S: Call unmap

Makes nxt_end2end_tests -w pass all tests.

Also duplicates the MapRead wire tests for the write cases
