Fix cs_loader memory leak on failed script load.

[ROKUMATE]

Description

When LoadFromSourceFunctions in the C# loader encountered a compilation error, it returned false immediately without releasing the CSharpCompilation object or its MetadataReference array. Each MetadataReference.CreateFromFile holds a native System.Reflection.Metadata PE reader backing store. Summed across all runtime DLLs this produced the ~53 MB leak reported by AddressSanitizer.

Changes:

• LoaderBase.cs: null out references and compilation on every failure path and force a GC cycle before returning, so the native backing stores are freed before process exit.
• LoaderV2.cs: add CollectibleAssemblyLoadContext and switch MakeAssembly to use alc.LoadFromStream() instead of Assembly.Load(byte[]). This scopes compiled assemblies to a collectible context so they can be unloaded by the GC rather than being permanently rooted in the default context.
• lsan.supp: update comment to reflect that the Roslyn-induced leak is fixed at source; the System.Private.CoreLib.dll suppression now covers only intentional CoreCLR static-lifetime allocations.

Fixes #378

The command '/bin/sh -c cd $METACALL_PATH/build         && $METACALL_PATH/tools/metacall-build.sh ${METACALL_BUILD_TYPE} ${METACALL_BUILD_OPTIONS}' returned a non-zero code: 8

Built MetaCall with ASAN enabled inside Docker (.docker-compose.sh test-address-sanitizer), which compiles everything with -fsanitizer=address and runs the full test suite. ASAN instruments every memory allocation at runtime and reports leaks at process exit. metacall-cs-test — the test that loads and executes C# scripts through the cs_loader — passed with no leak report, confirming the 53 MB leak from the original issue is gone.

Here is the full review: 5a58da1

I have also done a long TODO in cmake scripts related to C#: 56c5223

I had to extend it and complete things that were remaining. If you have doubts feel free to ask, I am closing the PR.

@ROKUMATE I did another improvement: 5d57bb4

looking into it 👍🏼
