[ssu] Allow defining url domain to be used with specific credentials. Fixes JB#32346

Previously store-auth-repos could be only defined in repos.ini and each
new feature would need to add new line to that variable. This patch
allows repos.ini to define url domain,credential pairs that can be used
to say which credential is used when certain url domain is used.

This removes the need to touch repos.ini when bringing in new feature.

Repository selection in relation to device modes was not properly tested
so far. Having this tested is especially important for making sure
introducing repository isolation does not break anything -- and future
changes don't break repository isolation.

The URL resolver test used to compare empty values when running in-tree,
assuming sandbox was not set up properly. Running tests like this is no
longer supported, for running tests in-tree use the run-tests script in
top level which takes care of setting up sandboxes.

Move setDeviceMode to a int instead of custom type. Also make the
extended interface with edit mode specification available.

Rename private headers with _p suffix to make accidental inclusion into
public headers less likely
