.Net: Rename 'Skills' -> 'Plugins' - Part 1 (#2854)

### Motivation and Context

Rename `Skills` to `Plugins`. First sub task from
#2119.

### Description

This is the first PR

1. Move Core, Document, MsGraph and Web skill projects to a new
`Plugins` folder
2. Update Core, Document, MsGraph and Web projects to use `Plugins`
instead of `Skills` in assembly names, namespace, class names
3. Extract text from `Skills.UnitTests` and create new
`Plugins.UnitTests` project
