VPR Pack: Replace hand-implemented linked lists to std::lists

[jmah76]

Related to PR #2084

Lists such as the ones vpr/src/base/vtr_types.cpp (line 236) might be better implemented as std::lists. Refer to #2084 (comment)

@jmah76 : were these mostly / all fixed (in which case we should close this issue), or is keeping it around worthwhile?

Sending this to @AmirhosseinPoolad .... updae some of the clustering data structs to use std::vector and std::list etc. Some have already been done, but more remain.

I ran clang-tidy to give me a list of all C-style arrays used in VPR. It's missing the heap allocated pointer arrays, still trying to find out if there's an easy way to list those. You can find results below.
