[maps] fix Air-gapped enviroment hitting 400 error loading fonts for layer (#165986)

Closes https://github.com/elastic/kibana/issues/165974

The root cause of the problem is calling `basePath.prepend` on a path
without a leading `/`. Maps is not consistent with path constants. Some
have leading `/` while others do not. To resolve the issue, this PR
updates all path constants to consistently have leading `/`.

PR adds functional test runner with `map.includeElasticMapsService:
false` to ensure maps is tested without EMS enabled to catch future
regressions.

### Test instructions
* set *map.includeElasticMapsService: false* in kibana.dev.yml
* install sample data set
* create new map with documents layer
* Configure label styling
* Verify layer is displayed with labels
