Implement supported skipped InputHandler integration tests

Unskip CSI/OSC sequences that are safely ignored or no-op in xterm.js using assertNoModeChange, following the pattern from prior commits. Add window option integration tests for GetWinSizeChars (18t) and PushTitle/PopTitle (22t/23t). Keep skipped: XTHIMOUSE (parsed as scroll down), DECSLRM (parsed as SCOSC), DECGPCS/DECGRPM aliases (covered by mode 45/47 tests), and addon-only graphics sequences.
