The
[protocol](https://microsoft.github.io/debug-adapter-protocol//specification.html#Types_Source)
expects that `sourceReference` be less than `(2^31)-1`, but we currently
represent memory address as source reference, this can be truncated
either when sending through json or by the client. Instead, generate new
source references based on the memory address.
Make the `ResolveSource` function return an optional source.
Refactor code revolving source objects such that most logics will be
reused.
The main change is to expose a single `CreateSource(addr, target)` that
can return either a normal or an assembly source object, and call
`ShouldDisplayAssemblySource()` only from this function instead of
multiple places across the code.
Other functions can use `source.IsAssemblySource()` in order to check
which type the source is.
Show assembly code when the source code for a frame is not available in
the debugger machine
Edit: this functionality will work only when using
`stop-disassembly-display = no-source` in the settings
Fix#136492
After the fix:

The debug adapter protocol supports an option to provide formatting
information for a stack frames as part of the StackTrace request.
lldb-dap incorrectly advertises it supports this, but until this PR that
support wasn't actually implemented.
Fixes#137057
This moves all the common settings of the launch and attach operations
into the `lldb_dap::protocol::Configuration`. These common settings
can be in both `launch` and `attach` requests and allows us to isolate
the DAP configuration operations into a single common location.
This is split out from #133624.
Replace Get{Signed,Unsigned} with GetInteger<T> and return std::optional
so you can distinguish between the value not being present and it being
explicitly set to the previous fail_value. All existing uses are
replaced by calling value_or(fail_value).
Continuation of #129818
