Introduce gdb.interrupt
DAP cancellation needs a way to interrupt whatever is happening on
gdb's main thread -- whether that is the inferior, a gdb CLI command,
or Python code.
This patch adds a new gdb.interrupt() function for this purpose. It
simply sets the quit flag and lets gdb do the rest.
No tests in this patch -- instead this is tested via the DAP
cancellation tests.
