Handle STATUS_WX86_BREAKPOINT and STATUS_WX86_SINGLE_STEP in DebugLoop 

When aidbg (x64) debugs a 32-bit target under WoW64, software breakpoints
(int3) surface as STATUS_WX86_BREAKPOINT (0x4000001f) instead of
STATUS_BREAKPOINT (0x80000003), and the step-over single step as
STATUS_WX86_SINGLE_STEP (0x4000001e). Route both to the existing
breakpoint/single-step handling so breakpoints are consumed and restored
correctly; otherwise continue re-stops on the same address forever.
