[FEATURE] LoongArch64 flavor of libSkiaSharp and libHarfBuzzSharp

[4Darmygeometry]

Is your feature request related to a problem?

I need to programming Watt Toolkit in Loongson 3A6000 using AOSC OS on LoongArch, need SkiaSharp and HarfBuzzSharp

Describe the solution you would like

e.g. https://github.com/loongson-community/dotnet-unofficial-build has runtimes/linux-loongarch64 and runtimes/linux-musl-loongarch64. same thing can be done for SkiaSharp and HarfBuzzSharp. toolchains are available in Loongnix 25, AOSC OS, Deepin, Gentoo, ALT Linux, Alpine and so on.

ideally infra should be DRY'd so it's just a matter of adding a single line in shell or cake script for new platform: define_platform(dotnetArch, nativeArch, osName) {. ... expand ... } which will expand to rubberstamped stuff for clang -target .... e.g.

# existing
define_platform("arm64", "aarch64", "linux")
define_platform("arm64", "aarch64", "linux-musl")
define_platform("riscv64", "riscv64", "linux")
define_platform("riscv64", "riscv64", "linux-musl")

# for this feature request
define_platform("loongarch64", "loongarch64", "linux")
define_platform("loongarch64", "loongarch64", "linux-musl")

LoongArch 64 isn't RISCV 64, It's a new ISA Cored by Loongson Technology LLC.

Hi folks,

The builds are now available on the preview feed: https://aka.ms/skiasharp-eap/index.json
Let me know if version 3.119.0-preview.0.38 is now working again for you.

As soon as you let me know, I can release this to NuGet and then hopefully a stable version shortly afterwards.

Thank you.
The version 3.119.0-preview.0.38 works fine on loongarch64 here, and the operating system is Loongnix25.
