[Enhancement]: Add support for enabling/disabling optional regions

[obeliskm]

Description

AWS added four new API calls on Feb 13 2023:

GetRegionOptStatus
DisableRegion
ListRegions
EnableRegion

https://awsapichanges.info/archive/changes/0366a2-account.html

the Go SDK https://pkg.go.dev/github.com/aws/aws-sdk-go-v2/service/account and CLI (v2.10.0) were updated a couple of days later to support enabling/disabling optional regions, it would be nice if the AWS provider also supported this..

Affected Resource(s) and/or Data Source(s)

• aws_account_enable_region
• data.aws_account_regions
• data.aws_account_regionoptstatus # may not need to be exposed, could just be used by enable_region?

Potential Terraform Configuration

resource "aws_account_enable_region" "example" {
  account_id  = "111111111111"       # optional, defaults to current account
  region_name = "opt-in-region-name" # mandatory, eg "ap-southeast-4"
}

# There's some extra complexity because the account_id can only be supplied if you're in a Management account or delegated admin account for an Org - but presumably it's ok to just fail with an error from the underlying API call if a user tries to enable a region for another account when they're not in the correct management account.

data "aws_account_regions" "example" {
  account_id  = "111111111111"       # optional, defaults to current account
  region_opt_status_contains = [ ENABLED | ENABLING | DISABLING | DISABLED | ENABLED_BY_DEFAULT ]
}

Then ideally then we'd be able to use this to setup provider aliases for each region - something like

provider "aws" {
  for_each = data.aws_account_regions.example
  alias  = each.key
  region = each.key
}

but I'm aware that is outrageous levels of scope creep that likely is impossible, so I only mention it as an idea.
