[FEATURE] riscv64 flavor of libSkiaSharp and libHarfBuzzSharp

[kasperk81]

Is your feature request related to a problem?

i want to use skiasharp on ubuntu 24.04 riscv64 desktop

Describe the solution you would like

e.g. https://nuget.info/packages/SQLitePCLRaw.lib.e_sqlite3/2.1.11 has runtimes/linux-riscv64 and runtimes/linux-musl-riscv64. same thing can be done for SkiaSharp. toolchains are available in modern ubuntu/debian, fedora and alpine.

for ref
ericsink/cb@fe4e425
ericsink/SQLitePCL.raw@685942a

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")

# for this feature request
define_platform("riscv64", "riscv64", "linux")
define_platform("riscv64", "riscv64", "linux-musl")

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.
