Port chromium (also chromium-based qt6-webengine) to loongarch64.

You can use git tags to find legacy version of patches.

Whole diff: chromium/chromium-VER.diff.

Partial diff: chromium/chromium-VER.*.diff, they are extracted from the whole diff.

Caveat:

• you need to build compiler-rt and rustc with -mcmodel=medium, otherwise it may fail to link due to relocation truncation.
• if you encountered error like undefined reference to __rust_dealloc, please update your GN version.
• you may need to modify NODE_VERSION in third_party/node/update_node_binaries to your nodejs version

Based on:

• loongson/electron
• loongson/chromium
• loongson/crashpad_la
• prcups/qt6-webengine-loongarchlinux
• various patches from linux distributions for building chromium with gcc/clang, e.g. Fedora and Debian
• llvm 16 files are generated by running third_party/swiftshader/third_party/llvm-16.0/scripts/update.py
• ffmpeg config files are generated by running configure with the arguments recorded in FFMPEG_CONFIGURATION (Chrome branding has aac and h264 enabled --enable-decoder='aac,h264' --enable-demuxer=aac --enable-parser='aac,h264', while Chromium does not) and copying the generated files
