chore: Implements no-op resource and run test with resource

[lantoli]

Description

• Implements no-op resource and run test with resource.
• Using static .json files in testdata to simulate a real response and avoid hard-coding too many values (will be removed in later PRs)
• resource_schema.go is still a WIP with a lot of TODOs. Changes are tracked here
• experimenting with new naming format for converting model_xxx
• only includes conversions from sdk -> TFModel follow up issue for update and more conversions

In order to run tests locally:

make enable-advancedclustertpf   # only once

ACCTEST_PACKAGES=./internal/service/advancedclustertpf ACCTEST_REGEX_RUN='TestAccAdvancedCluster_basic' make testacc
