Tested build on win-x64, osx-arm64 and ubuntu-arm64. This should make it easier to use when doing performance testing, which has to be done on release build. This could also facilitate adding release pipelines on desktop and also doing automated perf runs. |

Pull Request Overview
This PR enables the CoreCLR interpreter to be built on Release configurations for desktop platforms where it was previously a Debug-only feature. The interpreter remains enabled by default on platforms that require it (WASM/iOS) and on Debug desktop builds, but can now be explicitly enabled on Release desktop builds using the new --clrinterp build flag.
Key Changes
- Added a new
--clrinterpbuild flag to enable the interpreter in Release configurations - Updated platform-specific assembly offsets to support interpreter in Release builds
- Configured CMake to pass the FeatureInterpreter flag when the build option is specified
