fix(deps): patch rustls-webpki panic on malformed CRL (GHSA-82j2-j2ch-gfr8)

Switch aws-config and aws-sdk-kms from the `rustls` feature to
`default-https-client`, moving off the legacy rustls 0.21 stack
(rustls-webpki 0.101.7) to the modern aws-smithy-http-client stack
backed by rustls-aws-lc on rustls-webpki 0.103.13.

Removes rustls 0.21, rustls-webpki 0.101.7, hyper 0.14,
hyper-rustls 0.24, tokio-rustls 0.24, h2 0.3, and sct 0.7
from the dependency tree. Resolves Dependabot alert #16.
