[lldb][sbdebugger] Match progress category enum bit in Debugger.h

When the `eBroadcastBitProgressCategory` bit was originally added to
Debugger.h and SBDebugger.h, each corresponding bit was added in order
of the other bits that were previously there. Since `Debugger.h` has an
enum bit that `SBDebugger.h` does not, this meant that their offsets did
not match. This commit changes it so that the bit offsets match each other.
