Remove unused functions found by linter

Removed deprecated functions that were replaced by CallOrSelect:
- generateSelector() - replaced by generateCallOrSelect()
- generateCall() - replaced by generateCallOrSelect()
- normalizeWhitespace() - unused test helper

All tests still passing (9 parser + 20 codegen).
