Explicitly specify dependencies for each target/module

[cgrindel]

Describe the bug
We would like to build with explicit modules enabled.

To Reproduce
Steps to reproduce the behavior:

1. Execute the build with these flags: swift build --use-integrated-swift-driver --experimental-explicit-module-build

Expected behavior
It should succeed

Setup (please complete the following information):

• OS: MacOS 14.0
• Version of soto: 6.8.0
• Swift: 5.9

swift-driver version: 1.87.1 Apple Swift version 5.9 (swiftlang-5.9.0.128.108 clang-1500.0.40.1)
Target: x86_64-apple-macosx14.0

Additional context
I am willing to take a crack at reworking the Package.swift to explicitly specify the dependencies. Just let me know.

Related to cgrindel/rules_swift_package_manager#647.

It looks like a number of dependencies will need to be updated, as well.

[cgrindel]

On second thought, it looks like getting this and all of the transitive dependencies to build with swift build --use-integrated-swift-driver --experimental-explicit-module-build might be premature. Alternatively, could we update Package.swift to include all of the direct dependencies for each target?

The Package.swift is auto-generated by the swift script scripts/generate-package.swift. It uses the template scripts/templates/package.swift. So you'll need to edit that and run the above script.
