names: Add option for setting global DNS-over-TLS preference
Tests:

- Visit the names app. New 'Domains' heading and configuration section appear.

- DNS-over-TLS configuration option is as expected.

- When the configuration file does not exist, the option selected is 'no'.

- When the configuration option is changed, 'resolvectl' shows the newly set
configuration. Using 'resolvectl query {domain}' does not work when DoT is on
and server does not support DoT. 'opportunistic' and 'no' work on those cases.

- When a DNS server supporting DoT (such as 1.1.1.1) is manually set, resolution
with all three settings works.
