Add support for S3 Express One Zone (#3465)

## Motivation and Context
Allows the Rust SDK to use [S3 Express One
Zone](https://aws.amazon.com/s3/storage-classes/express-one-zone/)

## Description
The PR adds the said S3-specific functionality to the Rust SDK. The code
changes have already been reviewed by previous sub PRs, but it's worth
going through them again as a whole:

- https://github.com/smithy-lang/smithy-rs/pull/3388
- https://github.com/smithy-lang/smithy-rs/pull/3390
- https://github.com/smithy-lang/smithy-rs/pull/3432
- https://github.com/smithy-lang/smithy-rs/pull/3433
- https://github.com/smithy-lang/smithy-rs/pull/3459
- https://github.com/smithy-lang/smithy-rs/pull/3457
- https://github.com/smithy-lang/smithy-rs/pull/3462

In addition to the PRs above, commit eebe8af increases the canary
lambda's memory size to 512MB from 128MB (also makes it configurable
through a command line arg for `canary-runner`). By default, lambda's
allowed memory size is 128MB but with the addition of `canary-wasm` in
main, canary lambda's memory usage will be 152MB, causing the lambda to
be killed by a signal during runtime. The commit addresses that issue.

## Testing
- Unit tests in
[aws/rust-runtime/aws-inlineable/src/s3_express.rs](https://github.com/smithy-lang/smithy-rs/blob/7f8c28b7038372927ec6196eff88384452f908dd/aws/rust-runtime/aws-inlineable/src/s3_express.rs)
- Integration tests in
[aws/sdk/integration-tests/s3/tests/express.rs](https://github.com/smithy-lang/smithy-rs/blob/7f8c28b7038372927ec6196eff88384452f908dd/aws/sdk/integration-tests/s3/tests/express.rs

)
- Canary in smithy-rs#3462
