Adapt FindTBB.cmake also to oneAPI distributed TBB

[ataketa]

FindTBB.cmake identifies the tbb version with include/tbb/tbb_stddef.h.
In the new oneAPI distributed TBB, the version information is in include/oneapi/tbb/version.h.
This issue adapts FindTBB.cmake also to new oneAPI distribution.

Hi @AAAlvesJr , could you commit the following cmake code?

   if(TBB_INCLUDE_DIRS)
     if(EXISTS "${TBB_INCLUDE_DIRS}/tbb/tbb_stddef.h")
       file(READ "${TBB_INCLUDE_DIRS}/tbb/tbb_stddef.h" _tbb_version_file)
     elseif(EXISTS "${TBB_INCLUDE_DIRS}/oneapi/tbb/version.h")
       file(READ "${TBB_INCLUDE_DIRS}/oneapi/tbb/version.h" _tbb_version_file)
     else()
       message(FATAL_ERROR "The TBB_INCLUDE_DIRS ${TBB_INCLUDE_DIRS} is not correct.")
     endif()
     string(REGEX REPLACE ".*#define TBB_VERSION_MAJOR ([0-9]+).*" "\\1"
         TBB_VERSION_MAJOR "${_tbb_version_file}")
     string(REGEX REPLACE ".*#define TBB_VERSION_MINOR ([0-9]+).*" "\\1"
         TBB_VERSION_MINOR "${_tbb_version_file}")
     string(REGEX REPLACE ".*#define TBB_INTERFACE_VERSION ([0-9]+).*" "\\1"
         TBB_INTERFACE_VERSION "${_tbb_version_file}")
     set(TBB_VERSION "${TBB_VERSION_MAJOR}.${TBB_VERSION_MINOR}")
   endif()
