Handle general expression statements

[danielgaskins]

Summary

• evaluate and discard standalone expressions instead of assuming every expression statement is a function call
• preserve operations produced by subroutine and extern calls
• apply the same behavior inside OpenPulse calibration blocks while retaining specialized handling for pulse functions
• validate unknown gate names before their operands so the error identifies the gate

Testing

• pytest -q tests
• pytest -q --cov=pyqasm --cov-report=term tests
• isort --check-only src tests bin examples
• black --check --target-version py310 src tests bin examples
• pylint src tests bin examples
• mypy src examples
• qbraid admin headers src tests bin examples --skip=src/pyqasm/_version.py --type=apache
• sphinx-build -W -b html docs /tmp/pyqasm-388-docs

Closes #388
