[compiler-rt][scudo] Add CMake presets for standalone builds (#221089)

Add CMakePresets.json under compiler-rt to configure and test Scudo
standalone without requiring a full LLVM monorepo build. Includes
scudo-debug, scudo-release, and test presets. Used Gemini to clean up
and make the presets more generalized.
