sal/vcl: Win64 (x64) runtime source fixes -- thread key + window pointers

Pointer-width fixes on the runtime boot path (all compile unchanged on x86;
dmake-backportable):

- sal osl/thread.h: oslThreadKey sal_uInt32 -> sal_uIntPtr. The w32
osl_createThreadKey returns a heap PTLS* stuffed into the key; on LLP64 that
64-bit pointer was truncated, so osl_getThreadKeyData dereferenced garbage
(first crash: cppu getIdContainer during InitVCL). Not present in
origin/windows-amd64 (their thread.h/.c match trunk) -- authored here.
- vcl win/saldata: ImplSet/GetWindowLong -> LONG_PTR + Set/GetWindowLongPtrW,
SetWindowPtr/SetSalObjWindowPtr (LONG)->(LONG_PTR) (frame pointer stored in the
window's extra bytes was truncated -> sign-extended garbage in
UpdateFrameGeometry) (ref 9b64d14c8d); SAL_FRAME/OBJECT_WNDEXTRA sizeof(DWORD)
-> sizeof(ULONG_PTR) so the 8-byte pointer fits the reserve (added beyond the
reference, which relied on Windows over-allocating); ImplSendMessage BOOL ->
LRESULT (WinSalInstance::CreateFrame/CreateObject route the new
SalFrame*/SalObject* back as the SAL_MSG_CREATE* message result -- BOOL
truncated it, causing an AV in SalFrame::SetCallback; also fixes the latent
HDC/HWND truncations at the other call sites).
