estd::variadic::visitor performance evaluation

[malachib]

I as a developer want to know how visited types against an index perform as compared to a traditional switch so as to identify its suitability for constrained device usage

ACCEPTANCE CRITERIA

1. Output artifact is MD document indicating results on esp32, x64 and AVR platforms

USE CASE (not specifically criteria)

• J1939 code base has a massive switch statement; in theory the code code be cleaned a bit by using variant_storage and an index visitor - but code bloat is a concern
