[casadi] first step (no dependencies)

[jgillis]

• Changes comply with the maintainer guide.
• The name of the port matches an existing name for this component on https://repology.org/ if possible, and/or is strongly associated with that component on search engines.
• Optional dependencies are resolved in exactly one way. For example, if the component is built with CMake, all find_package calls are REQUIRED, are satisfied by vcpkg.json's declared dependencies, or disabled with CMAKE_DISABLE_FIND_PACKAGE_Xxx.
• The versioning scheme in vcpkg.json matches what upstream says.
• The license declaration in vcpkg.json matches what upstream says.
• The installed as the "copyright" file matches what upstream says.
• The source code of the component installed comes from an authoritative source.
• The generated "usage text" is accurate. See adding-usage for context.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Only one version is in the new port's versions file.
• Only one version is added to each modified port's versions file.

It might be more practical to format the portfile with spaces, not tabs. (Tabs are subject to settings. GH PR review looks strange.)

I see a lot of find modules. I would expect a similar set of dependencies in the manifest.

[dg0yt]

Maybe put the PR in draft state as long as it is not ready for review.

@dg0yt Thanks for your review, I assumed you would not start a review while CI still runs..

CasADi works with a plugin system.
The core is basically dependency-free.
In this first version, I'm packaging the 'core' feature set.
Next up would be coin-or-ipopt dependency, but that's for another PR.
Because of the plugin system, static libraries do not currently make sense.

I'll think about adding the namespace upstream.

@dg0yt The CI checking seems to stall; x64_linux is compiling whole of llvm, and windows builds queue until timeout.
Is this a normal state of affairs or am I just unlucky?

[dg0yt]

CI has a real problem.
llvm:x64-linux is building because the PR touches ci.baseline.

Oh I see, thanks for helping out this vcpkg noob.
