Feature Request: Extend `LiteralDict` lowering support

[m-akhil-reddy]

Summary

Recently, minimal lowering support for astx.LiteralDict was added to LLVMLiteIRVisitor (PR #175).

The current implementation intentionally supports only a small subset of cases:

• Empty dictionaries.
• Dictionaries with homogeneous constant key/value pairs.

For other cases (e.g., heterogeneous types or non-constant elements), the implementation currently raises a TypeError to keep the scope minimal.

Motivation

To make LiteralDict more useful, it would be helpful to extend support to additional scenarios.

Possible Extensions

Some potential follow-ups could include:

• Support for heterogeneous key/value types.
• Support for non-constant elements.
• Lowering using runtime construction (e.g., alloca + stores).
• Handling dictionary mutability or updates.
• Alignment with how other literal containers (e.g., lists/tuples) are lowered.

Goal

Gradually extend LiteralDict lowering while keeping the implementation consistent with the existing IR generation patterns in LLVMLiteIRVisitor.
