Initial Export Llama Lib support for Executorch (#30557)
### Details:
- "aten.scalar_tensor.default" is already supported by pytorch frontend.
But some ops seems to have "scalar_tensor.default" ops in executorch
flow which uses same translation as "aten.scalar_tensor.default". The PR
only adds "scalar_tensor.default" into the supported ops list and op
translation table.
- This PR impacts executorch llama support with export llama lib.
Update: Support for some additional ops (aten.absolute, aten.prod,
aten.prod.dim_int) added.
Added support for yolov12 as well.
