hGreat idea! I'm surprised we weren't already stripping all the binaries in site-packages. Good find.

What does this PR do?
Applies
strip --strip-unneededto all.sofiles included in the Python lambda layer.Motivation
Frequent increases in Python lambda layer size, exceeding checks.
Stripping binaries further (originally only applied
strip --strip-debug) can reduce the unzipped layer size by about 2.5MB.Testing Guidelines
Ran serverless e2e tests and manually inspected traces on a Python sample app. Manually checked that profiling and appsec still produced appropriate output. Used layer
arn:aws:lambda:us-west-2:425362996713:layer:Python312-strip-unneeded-rithika:1on an ARM Python 3.12 lambda function.Additional Notes
