Upgrade to TypeScript 7 (#34208)

* Upgrade to TypeScript 7

for massive tsc speed gains

Those on WebStorm will want to upgrade to EAP to reap the benefits of the new TSGo compiler

Some things (module-api & shared-components) which utilise unplugin-dts (and api-extractor) need to hold a copy of ts6 for its conventional lib format and API. TS7 ships with no API until TS7.1.

Other things which use eslint also need ts6 for typescript-eslint.

Some type changes were necessary as TS7 caught some issues.

* Add knip exception

* Fix bad merge
