[lldb-dap] Support column breakpoints (#113787)

This commit adds support for column breakpoints to lldb-dap.

To do so, support for the `breakpointLocations` request was
added. To find all available breakpoint positions, we iterate over
the line table.

The `setBreakpoints` request already forwarded the column correctly to
`SBTarget::BreakpointCreateByLocation`. However, `SourceBreakpointMap`
did not keep track of multiple breakpoints in the same line. To do so,
the `SourceBreakpointMap` is now indexed by line+column instead of by
line only.

See http://jonasdevlieghere.com/post/lldb-column-breakpoints/ for a
high-level introduction to column breakpoints.

[lldb] Replace assertEquals with assertEqual (NFC) (#82073)

assertEquals is a deprecated alias for assertEqual and has been removed
in Python 3.12. This wasn't an issue previously because we used a
vendored version of the unittest module. Now that we use the built-in
version this gets updated together with the Python version used to run
the test suite.
