chore(hybridcloud) Merge customer-domains feature into multi-region (#72902)

To reduce the number of features flags and the combinations of feature
flags, I am merging the `customer-domains` feature into
`system:multi-region`.

I've started to cleanup some of the logic around customer-domains
behavior as we'll no longer have ways to go in and out of customer
domains for specific organizations. There is more to do here and I'll do
the remaining cleanup once customer-domains feature can be removed.

These changes also include moving away from `window.__initialData` being
used across the application. Instead we can use `ConfigStore` to read
application configuration.
