* Add ppid to win32 debug and 'dp''s display/json ##debug
* Add process selection to w32 debug ##debug
Previously, `dp=` wouldn't fully switch to the given process since it
was treated like `dpt` thread switching, leaving the debugger in
an undefined state.
The user was interrupted during continue and switched to a different
thread since DebugBreakProcess creates a thread that triggers a breakpoint.
With these changes the DebugBreak thread is recorded to skip the breakpoint
event afterwards.
* Fixed w32dbg breaking issues and moved break_push to w32_dbg_wait to support stepping as well
Previously, breaking would only work during 'dc' because it was pushed
in debug.c specifically for continue. This change moves the
responsibility of pushing/popping w32_break_process_wrapper to
windows_debug.c instead to support calls to w32_dbg_wait from anywhere.
* Fixed issues in windows thread switching by implementing thread attach for w32dbg =!pid
Previously the function attempted to OpenProcess even though the main
pid is already opened by __open and the fact that re-opening the main
pid wouldn't do anything. This way it attaches to new threads when
called by r_debug_select.
* Modified w32_continue to update rio->pi.dwThreadId after switching to the requested thread
Manually changing iop->pi.dwThreadId in io_w32dbg's =!pid created a
problematic scenario when w32_continue is called with the last event's
tid from dbg_wait. This solution makes sure iop->pi.dwThreadId keeps
being updated after events on other threads arrive and that w32_continue
actually uses the given tid.
* Modified w32_continue return values
