@lonerOrz after this pr, cargo check on linux ci failed.
I guess we need to add freetype in linux runner's deps.

The libfreetype-dev package in Ubuntu 22.04 is too old. We can enable the bundled feature for cargo check to build with a bundled version of FreeType instead.

Plan to enable bundled freetype for github release ci.
use system freetype in fmt/check/clippy.

Ubuntu 22.04 requires manually enabling --features bundled; after that, it can be built successfully
