Drop interactive/dev-only stdlib modules from embedded packages

Running an app in embedded mode never enters the interactive REPL, so the REPL/dev-only
modules are dead weight. Confirmed via import trace (a plain script imports none of them;
site.py only touches _pyrepl/rlcompleter inside the interactive hook). Remove from all
platform excludes: _pyrepl (~300 KB), rlcompleter, tabnanny, the easter eggs this/
antigravity, and the frozen demo modules __hello__/__phello__.

Deliberately kept (a library or breakpoint() may import them): unittest (mock), pdb/bdb,
pydoc, doctest, code/codeop, multiprocessing, venv.
