[eem] rename asset_manager to entity_manager (#186617)

## Summary

Renames the experimental asset_manager plugin (never
documented/officially released) into entity_manager. I've used `node
scripts/lint_ts_projects --fix` and `node scripts/lint_packages.js
--fix` to help with the procedure and also renamed manually the
asset_manager references left.

The change also removes the deprecated asset_manager code, including the
`assetManager.alphaEnabled` plugin configuration. This means
entityManager plugin will be enabled by default.
