  [lldb] [disassembler] chore: enhance VariableAnnotator to return structured data: introduce VariableAnnotator::AnnotateStructured method (#169408)

## Description
Contribution to this topic [Rich Disassembler for
LLDB](https://discourse.llvm.org/t/rich-disassembler-for-lldb/76952),
this part.
```
The rich disassembler output should be exposed as structured data and made available through LLDB’s scripting API so more tooling could be built on top of this
```

----

This pr introduces new method `AnnotateStructured` in
`VariableAnnotator` class, which returns the result as a vector of
`VariableAnnotation` structured data, compared to original `Annotate`.

Additionally structured data is enhanced with information inferred from
`DWARFExpressionEntry` and variable declaration data.

I have moved this part of functionality form a bigger pr
https://github.com/llvm/llvm-project/pull/165163 to make it easier to
review, deliver smaller chunk faster in an incremental way.

## Testing
Run test with
```sh
./build/bin/lldb-dotest -v -p TestVariableAnnotationsDisassembler.py lldb/test/API/functionalities/disassembler-variables
```

all tests (9 existing) are passing.
