fix(vertexai): implement Read for EndpointWithModelGardenDeployment

[syangcode]

The resource is generated with exclude_read: true, so the generated Read is a no-op (return nil). State is never reconciled against the live Endpoint, so out-of-band changes go unnoticed and terraform plan reports "No changes" even when the deployment has drifted.

This wires Read up, but reads back only the replica counts.

Why only the replica counts

Almost every field on this resource is immutable. The only ones the API can change in place are those mutateDeployedModel accepts, which #18116 already wired into Update. A difference anywhere else could only mean the deployment was replaced out of band, and that case is already covered by clearing the id when the DeployedModel is gone.

This covers the drift-detection half of hashicorp/terraform-provider-google#27250. The in-place update half shipped in #18116.

vertexai: fixed `google_vertex_ai_endpoint_with_model_garden_deployment` not detecting drift in replica counts, because the resource had no Read implementation; out-of-band changes to `min_replica_count`, `max_replica_count` and `required_replica_count` are now surfaced on `terraform plan`

Testing

Tested by hand against a live deployment (paligemma-224-float32 on g2-standard-12 + NVIDIA_L4, us-west1):

1. After apply, state and the API both report min/max = 1 2.
2. terraform plan is clean, exit 0. Worth checking separately from step 4, since a decoder that catches real drift but also introduces phantom diffs would be a net regression.
3. Bumped maxReplicaCount to 4 out of band via endpoints:mutateDeployedModel.
4. terraform plan exits 2 and reports ~ max_replica_count = 4 -> 2.

Step 4 exits 0 with "No changes" on released v7.42.0.

@syangcode do you know how we can fix the failing TestAccVertexAIEndpointWithModelGardenDeployment tests? We are making a significant change to the ModelGardenDeployment resource, so now is the time to repair them.

[syangcode]

@c2thorn, I believe these tests require the L4 GPU quota in your CI projects, Could you please run

gcloud alpha quotas info describe CustomModelServingL4GPUsPerProjectPerRegion \
  --service=aiplatform.googleapis.com --project=ci-test-project-188019

And increase the quota for us-central1 region? Thanks

doubled the quota from 28 -> 56. I'll retry.
