Don't build and publish libcoreclr libeventprovider libeventpipe as crosscomponents on ARM (dotnet/coreclr#19782)

* Use _install to stop copying sosdocsunix.txt to crosscomponents directory in src/ToolBox/SOS/Strike/CMakeLists.txt
* Use _install for coreclrpal in src/pal/src/CMakeLists.txt
* Use _install for eventprovider in src/scripts/genLttngProvider.py
* Unconditionally use add_library_clr and _install for eventpipe in src/scripts/genEventPipe.py
