feat: avm/res/api-center/service initial implementation

[maciejporebski]

Description

Initial implementation of avm/res/api-center/service module proposed in Azure/Azure-Verified-Modules#2500.

Design Decisions

• The template abstracts away the "workspace" sub-resource, as only a single 'default' one is currently supported with no published plans to support additional ones at the moment. The inclusion of additional non-default workspaces can be added in the future by introducing an additional parameter and continuing to use the current parameters for deployment of the default workspace.
• API Sources (Microsoft.ApiCenter/services/workspaces/apiSources) has been included using a preview API version. No stable version currently exists for the type, but the type is key for most API Center deployments. While the type requires a preview API version the underlying feature itself is not in preview.

Known Issues

• Purging API Center workspaces does not currently work. To prevent soft-deleted workspaces from failing tests the resource names are suffixed with a string derived from the deployment name. This can be replaced by a purge operation once the RP fixes/implements the purge operation. ([BUG] API Center - Deleted Services - multiple endpoints broken azure-rest-api-specs#43339)
