ARMv8 optimized Dilithium (#1194) 
* Updated sig templates to add support for arch specific upstreams. Currently behaves as expected, but still need to test (and integrate) dilithium

* Fixed a couple of build errors, and started work on dilithium integration from pqclean. Currently failing kat tests

* Updated templating for both sig and kem to make them look a little better

* Renamed dilithium folders so they are consistent across pqclean and pqcrystals so that copy_from_upstream script will function correctly

* Added arm optimized version of dilithium[2|3|5]

* Updating other signature schemes CMakeLists.txt to be the output of the updated templates

* Arm optimized implementation of dilithium is added, with randomized signing patched into it. copy_from_upstream script is working properly. Still need to update the update_docs scripts before ready to merge

* Finished updating docs scripts and yml files. Builds pass, so should be ready for a merge

* Fixed template issue with multiple compile flags

* Updated doc generation scripts so that all '_' in scheme names are replaced with '\_'
