* Conditions find_package hsakmt on the pressence of the target. * Move finding of clang/llvm-objcopy to a common place and use an in-tree target if available. * Add options for depending on in-tree device libs. This is a roll-up of changes that I needed to do in order to build ROCR-Runtime with other parts of the toolkit. In my final arrangement, I am only using the first point, but I believe the second/third are general improvements -- so including those as well.

The find_package should be disabled by the superproject either by using the OVERRIDE_FIND_PACKAGE in FetchContent_Declare or by using the register_source_package function as described here:
function(register_source_package NAME)
file(WRITE "${CMAKE_BINARY_DIR}/__pkg/${NAME}/${NAME}Config.cmake" "")
set(${NAME}_DIR ${CMAKE_BINARY_DIR}/__pkg/${NAME} CACHE PATH "")
endfunction()

We should not be checking for if(TARGET) as this would require the superproject to order the add_subdirectory based on the dependency order. This can be quite fragile as we would need to change the order if the dependencies between components change. Instead we should just let cmake order the dependencies.
