Vadim Zeitlin bd7cea0ea6 Split wxWakeUpPipe class in MT-unsafe and MT-safe parts.
This class can also be useful when it's used in the main thread only, so
leave the lock-less part of the code in wxWakeUpPipe and derive a separate
wxWakeUpPipeMT from it for the use in wxConsoleEventLoop where it can be used
by multiple threads.

See #10258.
