Cherry-pick of #7748.

Explanation: This feature was specified in the corresponding proposal for Swift SDKs:

For Swift SDKs installed from remote URLs an additional --checksum option is required, through which users of a Swift SDK can specify a checksum provided by a publisher of the SDK. The latter can produce a checksum by running swift package compute-checksum command (introduced in SE-0272) with the Swift SDK bundle archive as an argument.

Currently, swift package compute-checksum is unable to handle .tar.gz bundles, which is a commonly used format for Swift SDKs. We're fixing that here by adding correct and unified handling for archive extensions.

This change is isolated to the swift package compute-checksum subcommand. The --checksum option is added in a subsequent PR: #7722.

Scope: Isolated to swift package compute-checksum subcommand.
Risk: Low, no existing behavior is
Testing: Automated test cases modified/added and passing in a subsequent PR: #7723
