This seems silly, but I guess in AWS it is a thing that these two values may
be different. Consumers of awshttp have the option of ignoring this, which
should be correct most of the time. Aws.zig will, however, use the service
metadata to do the right thing
This increases compilation time significantly as all 260+ services
need to be analyzed by zig during compilation. I plan to change
the model from a single "services" constant to a function
that will import only services that plan to be used. This
might be in addition to the single constant to allow
consumers to choose short compile times or all services
support
