Use for_each instead of count

[Nuru]

what

• Optionally use for_each instead of count when creating routes
• Avoid setting transit_gateway_default_route_table_association and transit_gateway_default_route_table_propagation in aws_ec2_transit_gateway_vpc_attachment

why

• Avoid unnecessary changes when making necessary ones
• These were not previously configurable (always set to false) and configuring them is not supported when using Resource Access Manager, so setting them false caused Terraform to always plan changes to them. At least by leaving them unset/default we can avoid constant plan changes.
