Support for Azure Resource Graph queries

Would you be interested to add support for querying Azure Resource Graph in this provider?

Using `azapi_resource_action` won't work as it does not handle the pagination of the response:

```terraform
# This does not work due to pagination requirements.
data "azapi_resource_action" "arg_query" {
type = "Microsoft.ResourceGraph/resources@2024-04-01"
action = "resources"
body = {
query <

WDYT?

API reference: https://learn.microsoft.com/en-us/rest/api/azureresourcegraph/resourcegraph/resources/resources?view=rest-azureresourcegraph-resourcegraph-2024-04-01&tabs=HTTP

Some example use cases:
1. Query Private Endpoints using Azure resource graph and create DNS records for it
2. Query resources by type and assign a policy to it

Start by examining the existing azapi_resource_action data source and the linked Azure Resource Graph REST API reference, focusing on pagination and request parameters. Add the proposed azapi_resource_graph_query data source with the shown query and management group inputs, and verify that paginated results are returned for the example use cases.
