Relates #23948.

Introduces a minimal first step for combining (using terraform-plugin-mux) into a single binary the current resource and data sources implemented using Terraform Plugin SDK v2 with other future implementations (such as using Terraform Plugin Framework).

This PR

• Adds to internal/provider a muxed provider factory that combines the current Terraform Plugin SDK v2 Provider implementation with 0 additional providers
• Invokes this muxed provider factory from the provider's main function

All existing acceptance tests will run unchanged. For example:

% make testacc TESTARGS='-run=TestAccVPC_basic' PKG=ec2
==> Checking that code complies with gofmt requirements...
TF_ACC=1 go test ./internal/service/ec2/... -v -count 1 -parallel 20  -run=TestAccVPC_basic -timeout 180m
=== RUN   TestAccVPC_basic
=== PAUSE TestAccVPC_basic
=== CONT  TestAccVPC_basic
--- PASS: TestAccVPC_basic (28.81s)
PASS
ok  	github.com/hashicorp/terraform-provider-aws/internal/service/ec2	35.228s

Subsequent Phases

• Replace use of acctest.ProviderFactories in acceptance tests with acctest.ProtoV5ProviderFactories (similar to Replace use of acctest.Providers with acctest.ProviderFactories #24680): Replace use of acctest.ProviderFactories with acctest.ProtoV5ProviderFactories #25733
• Introduce a skeleton Terraform Plugin Framework provider that imports no resources or data sources (see prototype: Mux with Terraform Plugin Framework #23948 for an example implementation) and add it to the mux: Provider multiplexing - Phase 1 #25715
