Add location to outputs on all modules which support it

[MariusStorhaug]

Description

As more complex deployments would require certain resources to be deployed into the same region as some other components, it would be better to dynamically be able to reference the location of where a module has been deployed, rather than reusing the RG.location, deployment.location or even use a param directly.

Suggestion:

• Add location as a parameter for all modules which support it
• Update module design guideline adding location as a new output for modules which support it.
• Add to the global.module.test.ps1 to check for location output where targetScope = 'blank' or 'resourceGroup' (not thought through how this would work for child resources).

@MariusStorhaug , note that not all resources support a location. Just pointing it out as you mention

Add location as a parameter for all modules
