Compress runtime/modules to reduce deployment package unzipped size

AWS Lambda limits ZIP deployment packages to 250 MB on-disk. The Linux PowerShell release builds are ~170 MB in the current release, which takes up ~70% of that cap. (Community members' attempts at producing "slim" PowerShell containers only reduce sizes by ~30MB, which isn't a ton in broader context.)

Pure PowerShell script modules are generally quite small, but compiled CLR module assemblies or autogenerated modules (e.g. `Microsoft.Graph.*`, `Az.*`, `AWS.Tools.*`) can get very large.

The current architecture only allows for ~80MB of module dependencies - `AWS.Tools.S3` and `Microsoft.Graph.Users` (with respective dependencies) breaches the 250MB cap.

Compressing the PowerShell runtime itself would:
* Free up >100MB of deployment package size (172MB vs 66 MB)
* Unblock build artifact verification (PowerShell publishes SHAs of release artifacts)

Supporting compressed module dependencies (e.g. `/opt/modules-packed.zip` or `/opt/modules-packed/*.nupkg` gets unpacked to `/tmp/modules-unpacked` and added to PSModulePath) could help the situation as well.
