Add ability to filter interpreted methods by assembly

[janvorli]

This change adds support for assembly name to the methodset stuff so that it can be used to select interpreted methods or methods to generate interpreter compilation dump for.

To preserve parity, I've made the same change to the JIT's version of the same functionality.

This change is a prerequisity for an upcoming change that enables running coreclr tests interpreted.

Pull Request Overview

This PR extends the method filtering and printing logic in both the JIT and interpreter to recognize and optionally include assembly names (using the ! delimiter) before class and method names. Key changes include:

• Introducing an m_containsAssemblyName flag and parsing ! in methodset initializers.
• Extending eePrintMethod, AppendMethodName, and PrintMethodName APIs to take includeAssembly and includeClass parameters.
• Updating call sites in JIT config, EE interface, and interpreter to propagate the new flags.

Comments suppressed due to low confidence (5)

src/coreclr/jit/jitconfig.h:25

• [nitpick] Consider adding a comment to explain the purpose and expected usage of m_containsAssemblyName, similar to the other boolean flags in this struct.

bool        m_containsAssemblyName;

src/coreclr/interpreter/interpretershared.h:85

• [nitpick] It would be helpful to document m_containsAssemblyName here, describing how it controls assembly-based filtering in the interpreter.

bool        m_containsAssemblyName;

src/coreclr/jit/jitconfig.cpp:53

• Add unit tests for JIT method filtering that include and exclude methods based on assembly names to verify the new flag behaves correctly.

name->m_containsAssemblyName = (exclamation != nullptr);

src/coreclr/interpreter/methodset.cpp:53

• Introduce tests for the interpreter MethodSet to ensure methods are filtered properly when an assembly name prefix is present.

name->m_containsAssemblyName = (exclamation != nullptr);

src/coreclr/jit/eeinterface.cpp:251

• [nitpick] Update this comment to mention that clsHnd may be NO_CLASS_HANDLE when includeClass is false, for clarity.

//    clsHnd                     - Handle for the owning class.

So in order to specifiy assembly the format would be DOTNET_Interpreter=TestAssembly.dll! ?

[jakobbotsch]

These docs should be updated:

https://github.com/dotnet/runtime/blob/b49ebac33e06556804af96afebbb8f706d51a2e2/docs/design/coreclr/jit/viewing-jit-dumps.md#specifying-method-names

So in order to specifiy assembly the format would be DOTNET_Interpreter=TestAssembly.dll! ?

It would be TestAssembly!*

So in order to specifiy assembly the format would be DOTNET_Interpreter=TestAssembly.dll! ?

No, only the assembly name would be there, so e.g. to specify all functions in one assembly, it would be DOTNET_Interpreter=TestAssembly!*

[janvorli]

@jakobbotsch good point, I'll update the docs.
