[1.20.4] [All] Feat: Common buffer interface (#80)

# Description

**What does this PR do?**
This pull request adds a new `IBuffer` interface that can be used for
any glMapBuffer compatible buffer target
It contains default implementation for buffer mapping in the client's
memory

It adds a new task shared by all environment in order to debug renderer
using [RenderDoc](https://renderdoc.org)
