What this PR does / why we need it:
This PR adds a proactive table existence check before attempting to create DynamoDB tables during feast apply. This enables Feast to work in environments where IAM roles don't have dynamodb:CreateTable or dynamodb:DeleteTable permissions, allowing organizations to manage DynamoDB tables exclusively through infrastructure-as-code tools like Terraform.
