- Move struct _TL and TL definitions from win32.h to ntuser.h.
- Modify the type of TL.pfnFree as newly-defined TL_FN_FREE function pointer.

This was introduced historically in commit 583de66b3 (r7460) to
workaround some compiler problems (or replace already existing
GCC-specific __attribute__((packed)) annotations); however these
structures are in-memory-only, do not describe any on-disk data
format and don't describe hardware-specific data. So they should
have the "natural" alignment of the target platform.
They also have to match the documented layouts at:
https://reactos.org/wiki/Techwiki:Win32k/THREADINFOhttps://www.geoffchappell.com/studies/windows/km/win32k/structs/threadinfo/index.htm
at least for the compatible parts that ReactOS shares.

- Rename CLIENTTHREADINFO::tickLastMsgChecked into timeLastRead as
documented in https://reactos.org/wiki/Techwiki:Win32k/CLIENTTHREADINFO .
This is the last time the message queue was read.
- This is the structure member one must compare against the current tick
count timestamp in order to heuristically determine whether a message
queue thread is hung!! Fix MsqIsHung() in accordance, add extra debug
logging in order to help us determining which of our code present
regular GUI hangs, and add as well an extra "TimeOut" parameter so as
not to hardcode a fixed value within that function but instead
allowing its caller to specify possible different values.
- THREADINFO::timeLast is on the contrary the last message time stamp,
and will definitively differ from CLIENTTHREADINFO::timeLastRead .
It should only be used for information purposes!
- Accordingly, in NtUserGetThreadState()::THREADSTATE_UPTIMELASTREAD
and in InitThreadCallback(), only (re-)initialize the timeLastRead
member of the CLIENTTHREADINFO structure of the THREADINFO of interest.
- In co_IntPeekMessage(), update more often the timeLastRead timestamp
whenever the current message queue has been read (but NOT timeLast!!
That one will be updated ONLY WHEN a message is found!).
- In co_IntSendMessageTimeoutSingle() first check whether the window to
which we send the message is being destroyed, before checking for
queue hangs etc. Collapse the logic checks for queue hang and increase
the hang timeout check to 4 times MSQ_HUNG (== 4 * 5 seconds) and
display a debug trace.
