Add Intel oneAPI packages (#20411)

This creates a set of packages which all use the same script to install
components of Intel oneAPI. This includes:

* An inheritable IntelOneApiPackage which knows how to invoke the
  installation script based on which components are requested
* For components which include headers/libraries, an inheritable
  IntelOneApiLibraryPackage is provided to locate them
* Individual packages for DAL, DNN, TBB, etc.
* A package for the Intel oneAPI compilers (icx/ifx). This also includes
  icc/ifortran but these are not currently detected in this PR
