LOG: [lldb] Use CreateOptionParsingError in CommandObjectBreakpoint (#83086)
This updates the remaining SetOptionValue methods in
CommandObjectBreakpoint to use CreateOptionParsingError.
I found a few minor bugs that were fixed during this refactor (e.g.
using the wrong flag in an error message). That is one of the benefits
of centralizing error message creation.
I also found some option parsing code that is written incorrectly. I do
not make an attempt to update those here because this PR is primarily
about changing existing error handling code, not adding new error
handling code.
