peter 42849e92a6 Improve readability of GPU architecture hardware specs (#3009) 
* move units of measurement to table headers

* add glossary explaining table headers

* add missed units and update h1

* toc listing to say indicate Accelerators & GPUs

* fix typo

* update meta description and keywords

* Update title in toc to fit in sidebar

* update title, toc, and filename

* Fix broken link to HIP programming guide

* Revert "update title, toc, and filename"

This reverts commit 6b9e687805.

* Revert glossary; slight fixes

* Change 'Pro' to 'PRO' for consistency

* Add references to programming and hardware architecture guides

* Change 'warp' to 'wavefront'
