Extend LiteralSet lowering support beyond homogeneous integer constants

[m-akhil-reddy]

Support for LiteralSet lowering could be expanded to handle more set literal scenarios.

Some useful additions would include:

• Mixed-width integer sets (e.g., i16 with i32)
• Non-integer constant sets (e.g., floats)
• Sets containing non-constant expressions that require runtime lowering
• Nested or more complex set literals

Extending the lowering logic to support these cases would allow LiteralSet to represent a wider range of set literals and improve overall completeness of the datatype support.

hi @yuvimittal ,
can you assign it to me.
