Do not compile in dlldata.c or ia2_api_all_c.c

These files are only required for a COM server, but since the
IAccessible2Proxy will actually be the effective server (inside our
process). We just have to make sure we respond to the correct events, and
reimplement the virtual functions as required.
This is already done, so these files can be removed.
