This moves the logic to compute the install prefix to a single location in the main config file. Extra config files can use the new AMENT_IMPORT_PREFIX variable, which simplifies the code and makes it more robust to future changes. The logic to compute AMENT_IMPORT_PREFIX has been taken from the CMakePackageConfigHelpers module. The code is well-tested and also handles symlink aliasing.

EDIT I renamed
AMENT_IMPORT_PREFIXto<package>_IMPORT_PREFIXbecause initially, I did not take recursivefind_package()calls into account, which may clobber a single global variable.
