Tasking: Add support for several compiler toolsets

Add support for the Tasking compiler toolset:

* TriCore Compiler Toolset 6.3 (with TriCore, ARM, MCS,
  8051 and PCP architecture compilers)
* SmartCode Compiler Toolset 10.1 (with TriCore, ARC, MCS,
  8051 architecture compilers)
* ARM Compiler 6.0
* MCS Complier 3.3
* 8051 Compiler 7.2

Fixes: #23756

+Select the Tasking toolset which provides the compiler
+
+Architecture compilers are provided by different toolchains with
+incompatible versioning schemes.  Set this variable in a
+:variable:`toolchain file <CMAKE_TOOLCHAIN_FILE>` so CMake can detect
+the compiler and version correctly. If no toolset is specified,
+``Standalone`` is assumed.
+
+Projects, that can be build with different architectures and/or toolsets, must
+take :variable:`CMAKE_TASKING_TOOLSET` and
+:variable:`CMAKE_<LANG>_COMPILER_ARCHITECTURE_ID` into account to qualify
+:variable:`CMAKE_<LANG>_COMPILER_VERSION`.
+
+``TriCore``
+  Compilers are provided by the TriCore toolset.
+
+``SmartCode``
+  Compilers are provided by the SmartCode toolset.
+
+``Standalone``
+  Compilers are provided by the standalone toolsets.
+
+  .. note::
+
+    For the TriCore architecture, the compiler from the TriCore toolset is
+    selected as standalone compiler.
