[Feature]: improve type-checking performance

[Hotell]

Library

React Components / v9 (@fluentui/react-components)

Describe the feature that you would like added

v9 and some cross project libraries/apps use TS path aliases, which provide excellent DX and blazing fast Application Bundling speeds with tools like swc or esbuild.

We also leverage TS solution config files within our libraries, and use tsc -b for type checking.

This inflicts huge performance penalty on type-checking execution, because TSC needs to traverse and parse all the paths on every run.

By stopping using TS path aliases mapped to source files on CI for type-checking, we can gain significant performance boost.
