How is the progress of coreclr interpreter implementation of .net10? Is it possible to try it?

Check the tracking issues #112748 #112158 and the label area-CodeGen-Interpreter-coreclr.

It can be opt-in via environment variable DOTNET_Interpreter=$(AssemblyName):

runtime/src/coreclr/interpreter/interpconfigvalues.h

Lines 22 to 30 in a90f7ab

	RELEASE_CONFIG_METHODSET(Interpreter, "Interpreter")
	CONFIG_METHODSET(InterpHalt, "InterpHalt");
	CONFIG_METHODSET(InterpDump, "InterpDump");
	CONFIG_INTEGER(InterpList, "InterpList", 0); // List the methods which are compiled by the interpreter JIT
	RELEASE_CONFIG_INTEGER(InterpMode, "InterpMode", 0); // Interpreter mode, one of the following:
	// 0: default, do not use interpreter except explicit opt-in via DOTNET_Interpreter
	// 1: use interpreter for everything except (1) methods that have R2R compiled code and (2) all code in System.Private.CoreLib. All code in System.Private.CoreLib falls back to JIT if there is no R2R available for it.
	// 2: use interpreter for everything except intrinsics. All intrinsics fallback to JIT. Implies DOTNET_ReadyToRun=0.
	// 3: use interpreter for everything, the full interpreter-only mode, no fallbacks to R2R or JIT whatsoever. Implies DOTNET_ReadyToRun=0, DOTNET_EnableHWIntrinsic=0

Currently only tests under src/tests/JIT/interpreter are supported.
