Add bug-fixed version of quantized convolution IP with kn2row and tiling

[ymd8bit]

Overview

This request mainly focuses on adding new quantized convolution IP called qconv_kn2row_tiling.
During my development, I've used linter in my environment (clang-format), so this seems to have many modified files that are not inherently important.
Also this request contains much context and some analysis I need to explain, so I described them in the following doc. Please quickly scan it, then check the modification if you'd like.

Can one of the admins verify this patch?

@tkclimb nice! 👍
will look more thoughtfully through it tomorrow...

@n-nez and me tried your branch with the correct .rbf and preloader manually. It works fine.
(we tried classification/lmnet_quantize_cifar10_space_to_depth with hq, ts and cache flags)

Seems that the testing code still using the old .rbf and preloader.
This path should also changed to point to the right hardware design:
https://github.com/tkclimb/blueoil/blob/add_qconv_kn2row_tiling/dlk/tests/testcase_dlk_base.py#L52

Maybe hw_path should point to dlk/hw/intel/de10_nano/qconv_kn2row_tiling/soc_system.rbf ? Please check that point.

run dlk test

@n-nez @antonionevado @lm-lily
Please review 👍👍👍

[n-nez]

@ruimashita Already approved it.

There are lots of unused code / unrelated changes under dlk/bakends, but we are going to fix it in following PRs. Instead of delaying this one. 😇

For the meaningful part of the code, everything is ok. 🙂

@n-nez
Because there are changes after your approved, I asked re-review again.

@ruimashita Yep, I know, I saw them too. 🙂
As it was @antonionevado @lm-konda and me who proposed these changes 😅 💪
