Remove FindTBB.cmake

Clean up, follow up of !1495 (merged). Tested with TBB 2020.3 and oneTBB 2021.10. Maybe the minimum required version of TBB needs to be changed in cmake/GaudiDependencies.cmake since it's quite an old one.

-# This find module file was originally found at

-
-# - Find ThreadingBuildingBlocks include dirs and libraries
-# Use this module by invoking find_package with the form:
-#  find_package(TBB
-#    [REQUIRED]             # Fail with error if TBB is not found
-#    )                      #
-# Once done, this will define
-#
-#  TBB_FOUND - system has TBB
-#  TBB_INCLUDE_DIRS - the TBB include directories
-#  TBB_LIBRARIES - TBB libraries to be lined, doesn't include malloc or
-#                  malloc proxy
-#  TBB::tbb - imported target for the TBB library
-#
-#  TBB_VERSION_MAJOR - Major Product Version Number
-#  TBB_VERSION_MINOR - Minor Product Version Number
-#  TBB_INTERFACE_VERSION - Engineering Focused Version Number
-#  TBB_COMPATIBLE_INTERFACE_VERSION - The oldest major interface version
-#                                     still supported. This uses the engineering
-#                                     focused interface version numbers.
-#
-#  TBB_MALLOC_FOUND - system has TBB malloc library
-#  TBB_MALLOC_INCLUDE_DIRS - the TBB malloc include directories
-#  TBB_MALLOC_LIBRARIES - The TBB malloc libraries to be lined
-#  TBB::malloc - imported target for the TBB malloc library
-#
-#  TBB_MALLOC_PROXY_FOUND - system has TBB malloc proxy library
-#  TBB_MALLOC_PROXY_INCLUDE_DIRS = the TBB malloc proxy include directories
-#  TBB_MALLOC_PROXY_LIBRARIES - The TBB malloc proxy libraries to be lined
-#  TBB::malloc_proxy - imported target for the TBB malloc proxy library
-#
-#
-# This module reads hints about search locations from variables:
-#  ENV TBB_ARCH_PLATFORM - for eg. set it to "mic" for Xeon Phi builds
-#  ENV TBB_ROOT or just TBB_ROOT - root directory of tbb installation
-#  ENV TBB_BUILD_PREFIX - specifies the build prefix for user built tbb
-#                         libraries. Should be specified with ENV TBB_ROOT
-#                         and optionally...
-#  ENV TBB_BUILD_DIR - if build directory is different than ${TBB_ROOT}/build
