Consolidate the BB10 Qt module sources into this repo alongside qtbase so the
full Qt6 cross-build is reproducible from one place (previously separate,
unpushed sibling repos that could be lost). v6.8.3 + BB10 patches:
- qtshadertools: SPIRV-Cross langinfo guard for QNX.
- qtmultimedia: drop QNX audio backend block.
- qtsvg/qtdeclarative/qthttpserver: pristine (no source patches needed).
