chore: Drop quota check validation

[Shreyas-Microsoft]

Purpose

This pull request removes the model deployment quota validation scripts and associated preprovision hooks from the Azure deployment pipeline. The changes simplify the deployment process by eliminating quota checks and related logic for AI model deployments.

Removal of quota validation logic:

• azure.yaml: Deleted preprovision hooks for both POSIX and Windows environments that ran the quota validation scripts during deployment.
• scripts/validate_model_deployment_quota.ps1: Removed the PowerShell script responsible for validating model deployment quotas. This script included logic for checking subscription quotas, parsing deployment parameters, and validating AI Foundry configurations.
• scripts/validate_model_deployment_quota.sh: Removed the Bash script counterpart for validating model deployment quotas. It performed similar functionality as the PowerShell script but was tailored for POSIX environments.

Removal of individual model quota validation scripts:

• scripts/validate_model_quota.ps1: Deleted the PowerShell script for validating individual model quotas, including logic for checking region-specific quotas and updating deployment parameters.
• scripts/validate_model_quota.sh: Removed the Bash script for validating individual model quotas, which handled quota checks and fallback logic for regions with insufficient capacity.

Does this introduce a breaking change?

• Yes
• No
