* 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
