Subject: [PATCH 1/4] [lldb][Commands] Show symbol change bit in SB API
This exposes the `eBroadcastBitSymbolChange` bit to the SB
API to show when a symbol change event has been broadcast as
this wasn't being done before. Also refactors `eBroadcastSymbolChange`
to `eBroadcastBitSymbolChange` to match the naming convention
for other event bits used in the debugger.
