fix(material/core): test environment check not picking up jest (#23722)

In #23636 the test environment check was changed so that it looks for the test objects either on `window` or `global`, however it looks like this isn't enough to pick up Jest which isn't published on either.

These changes simplify the setup by looking up the value globally and disabling the type checkng error with `@ts-ignore`. We can't use `declare const` for it, because it causes issues in g3.

I've also reverted some of the `any` types that had to be added in #23636.

Fixes #23365.
