skia: new recipe

[valgur]

Summary

Changes to recipe: skia/cci.20240727

Motivation

Skia is an open source 2D graphics library which provides common APIs that work across a variety of hardware and software platforms. It serves as the graphics engine for Google Chrome and ChromeOS, Android, Flutter, Mozilla Firefox and Firefox OS, and many other products.

• Closes [request] skia/latest #2389

Details

• he project provides two build systems - an older one based on gn and a newer one based on Bazel that the project is being migrated to. I opted for the latter because it has much better compatibility with Cona.
• The project builds and links against two Rust libraries internally: icu4x and vello.
• The build system also always downloads and uses a Clang toolchain for compilation. Will have to look into replacing it with the C++ toolchain from the Conan profile.
• I opted to build and export only a single bundled library instead of the numerous components it is composed of. The individual components could be added later, if there's interest.
• I'm quite happy with how much simpler the recipe is compared to the equivalent Vcpkg port (currently at least): https://github.com/microsoft/vcpkg/tree/master/ports/skia
• Requires dawn: new recipe #24735

For this reason you might find that not all the references have been launched or not all the configurations for a given reference. Also, take into account that we cannot guarantee the order of execution as it depends on CI workload and workers availability.}
