[Feature]: Add Patina Perf Shell App

[makubacki]

Feature Overview

In order to get more granular performance information about execution time for core services implemented in Patina, this issue tracks adding an EFI shell application that will invoke the boot services and runtime services and build performance result data so the data can be compared on a platform with the C DXE Core and Patina DXE Core and between different platforms that each use the Patina DXE Core.

Solution Overview

High-level request:

• An EFI application (ideally written in Rust)
• Invokes all boot and runtime services multiple times in a deterministic pattern to record an average time per service under conditions that may be impactful to the service's performance.
• A mechanism to output the perf data to a file that can be saved onto an attached storage device.
• An offline mechanism to convert the perf data file to a tabular/graphical view of the data.

Run shell app on physical platform with C DXE Core vs Patina DXE Core:

• Basic Service Test (all services implemented in Patina)
• Image Load Test

@berlin-with0ut-return, I know you are just sharing the output format right now, but when you have time, could you please show output from both the C DXE Core and Patina DXE Core and label the tables with the platform the data was acquired from?
