Pipe nvtx markers from Tripy to TRT engine

[parthchadha]

Goal: get kernel information for each frontend layer for easier performance debugging and directed unit tests (ex: MHA layer maps to a single fused kernel).

Tripy already passes loc attribute to stablehlo program that gets generated. We need to pipe the attribute information to TRT layer metadata and correlate the kernel information to the frontend APIs.
