Rémi Bernon 544fd9504a ntdll: Process system APCs while the signals are blocked.
This makes sure that system APC, such as APC_BREAK_PROCESS do not get
interrupted in the middle of their execution, and that the APC
completion notification is always correctly sent back to the caller.

Otherwise DbgBreakProcess sometimes did not return until
WaitForDebugEvent/ContinueDebugEvent are called, because of a race
condition between the APC servicing thread, and the newly created
exception thread.

Rémi Bernon 6cb2336217 ntdll: Reorder code to make the select logic clearer.
The wait_select_reply call may return STATUS_USER_APC/STATUS_KERNEL_APC,
depending on which APC is about to be returned but the apc call will
always be APC_NONE right after the wait. It needs an additional select
request to actually return the call.

Rémi Bernon 6672fc9d85 ntdll: Use custom internal zero_bits_64 parameter format.
The zero_bits parameter can be a pointer mask on Win64 and WoW64 and it
was incorrectly truncated to 16bits in APCs. Testing shows that only the
leading zeroes are used in the mask, so we can safely use the 64 based
number of leading zeroes everywhere instead.
