feat(python): enable compression in the official pypi package (#3145)

Enable TFLM compression support in the official Python package builds
by adding --//:with_compression=true to the bazel commands in
pypi_build.sh.

This ensures that:
- Users who install tflite_micro from PyPI can use compressed models
- The compression module functionality is available out of the box
- Both the wheel build and tests run with compression enabled

The Python package is primarily used for testing and development
on desktop/server systems, not on embedded targets. There's no
benefit to disabling compression support to save a few kilobytes
when the package runs on machines with gigabytes of RAM. Enabling
compression by default provides a better developer experience
without any practical downside.
