* Reuse computed checksums across retries

This commit adds the ability to reuse previously computed checksums for
a request across retries.

This ensures that if a request data stream is modified between attempts
that the server will reject the request.

As part of this change, the `http-auth-spi` package has been updated to
expose a new interface: `PayloadChecksumStore`. This is a simple storage
interface that allows signers to store and retrieve computed checksums.
Additionally, a new `SignerProperty` is introduced,
`SdkInternalHttpSignerProperty.CHECKSUM_CACHE` so that signers and
their callers can access this cache.

Note that both the interface and associated signer property are
`@SdkProtectedApi` and not intended to be used by non-SDK consumers of
`http-auth-spi`.

Finally, this adds a dependency on `checksums-spi` for `http-auth-spi`.

* Update core/sdk-core/src/main/java/software/amazon/awssdk/core/internal/http/pipeline/stages/SigningStage.java
