### Enhancement description

Based on [customer request](https://localstack-community.slack.com/archives/C0598EHPT1N).
Implement operation `scan` and `query` for global tables in DynamoDB service.

Test sample:

```shell
# Create a table
awslocal dynamodb create-table --table-name global01 --key-schema AttributeName=id,KeyType=HASH --attribute-definitions AttributeName=id,AttributeType=S --billing-mode PAY_PER_REQUEST --region ap-south-1

#Create replicas
awslocal dynamodb update-table --table-name global01  --replica-updates '[{"Create": {"RegionName": "eu-central-1"}}, {"Create": {"RegionName": "us-west-1"}}]'  --region ap-south-1


# Table can be operated on in all replicated regions
awslocal dynamodb list-tables --region eu-central-1

awslocal dynamodb put-item --table-name global01 --item '{"id":{"S":"foo"}}' --region eu-central-1
awslocal dynamodb describe-table --table-name global01 --query 'Table.ItemCount' --region ap-south-1

# Get all replicas
awslocal dynamodb describe-table --table-name global01 --query 'Table.Replicas' --region us-west-1


# Query in all regions
awslocal dynamodb query --table-name global01 --key-condition-expression 'id = :id' --expression-attribute-values '{":id":{"S":"foo"}}' --region ap-south-1
awslocal dynamodb query --table-name global01 --key-condition-expression 'id = :id' --expression-attribute-values '{":id":{"S":"foo"}}' --region eu-central-1
awslocal dynamodb query --table-name global01 --key-condition-expression 'id = :id' --expression-attribute-values '{":id":{"S":"foo"}}' --region us-west-1
```
