kobalicek b56f4176cb Codebase update and improvements, instruction DB update
* Denested src folder to root, renamed testing to asmjit-testing

  * Refactored how headers are included into <asmjit/...> form. This
    is necessary as compilers would never simplify a path once a ..
    appears in include directory - then paths such as ../core/../core
    appeared in asserts, which was ugly

  * Moved support utilities into asmjit/support/... (still included
    by asmjit/core.h for convenience and compatibility)

  * Added CMakePresets.json for making it easy to develop AsmJit

  * Reworked CMakeLists to be shorter and use CMake option(),
    etc... This simplifies it and makes it using more standard
    features

  * ASMJIT_EMBED now creates asmjit_embed INTERFACE library,
    which is accessible via asmjit::asmjit target - this simplifies
    embedding and makes it the same as library targets from a CMake
    perspective

  * Removed ASMJIT_DEPS - this is now provided by cmake target
    aliases - 'asmjit::asmjit' so users should not need this variable

  * Changed meaning of ASMJIT_LIBS - this now contains only AsmJit
    dependencies without asmjit::asmjit target alias. Don't rely on
    ASMJIT_LIBS anymore as it's only used internally

  * Removed ASMJIT_NO_DEPRECATED option - AsmJit is not going
    to provide controllable deprecations in the future

  * Removed ASMJIT_NO_VALIDATION in favor of ASMJIT_NO_INTROSPECTION,
    which now controls query, features, and validation API presence

  * Removed ASMJIT_DIR option - it was never really needed

  * Removed AMX_TRANSPOSE feature from instruction database (X86).
    Intel has removed it as well, so it's a feature that won't
    be siliconized
