Add APB verification components

[c-thaler]

I added APB master and slave VCs. The APB master is based on a VC that I used in a few of my designs.

Thanks @c-thaler, I will look into it! Please have a look at the VC standard being discussed #1017

[c-thaler]

Thanks. I had a look at it and I will start with implementing Rule 13 (single generic).

[c-thaler]

I've also implemented rules 10/15 (locking test runner cleanup gate while busy) and 14 (sync interface).

[LarsAsplund]

Please rebase on the vc_standard branch and you will get rid of the failing tests that have noting to do with this PR. You will also have access to the functions and types mentioned in the rules (located in vc_pkg.vhd

@LarsAsplund The idea is to use create_std_cfg within the constructor of my VC, right? That also means that the logger parameter can be removed from my VC's constructor?

[LarsAsplund]

I have two projects where this can be useful. I will have it tested there to see if there are issues to resolve.

[c-thaler]

Any news on this?

[LarsAsplund]

@c-thaler Unfortunately not. There are some good news though. VUnit will get funding from Chips JU which will start during the spring. One of our focus areas is verification components which means that there will be time available to address such issues.
