Fix an issue where the new style of generated block supporting code wasn't properly handled by the trimmer when using the dynamic registrar.
Add a 'link sdk' + 'link all' test variation for all platforms for monotouch-test.
Update a few tests to cope with the additional trimming variations for monotouch-test.

…forms for monotouch-test.

Pull request overview

This PR extends the xharness Jenkins test matrix for monotouch-test by introducing additional linker coverage across all platforms, adding explicit Link SDK and Link All runs (as Release variations). This fits into the tests/xharness infrastructure that defines how CI expands a single test project into multiple build/run configurations.

Changes:

Add Release|LinkSdk variation for monotouch-test.
Add Release|LinkAll variation for monotouch-test.

Use IsLinkAny instead of IsLinkAll for trimming guards, since SDK-level trimming (linksdk) can also remove framework references, properties, and delegate mismatch checking code from SDK assemblies. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

The PreserveBlockCodeStep only handled old-style block proxy types (with a Handler field and [MonoPInvokeCallback] attribute on Invoke). New-style block proxy types use [UnmanagedCallersOnly] on Invoke with no Handler field. When using linkall + dynamic registrar (the default on iOS simulator), the existing MarkForStaticRegistrar[Step] does not run (gated on RegistrarMode.Static), so the Invoke method was trimmed. At runtime, the reflection lookup in Blocks.GetBlockForDelegate would then fail with MX8060. Extend PreserveBlockCodeStep to also detect and preserve new-style block proxy Invoke methods, matching on [UnmanagedCallersOnly] and [UserDelegateType] attributes.
