Feature/lit 3918 no globalthis variables anymore

[FedericoAmura]

Description

This PR removes the global variables used in several to share configs between modules or helper functions
Also removes the cdn installation instructions as those depend on a now gone global variable
The intent for this is to allow consumers of the SDK to have multiple versions of it without conflicts

Changelog

• globalThis.litWCProvider from auth-browser package is gone
• added setMiscLitConfig function to pass litCore config up to misc package instead of relying on globalThis.litConfig

double checked that this variable is not used in other modules as it's now locally scoped instead of global
