[lldb] Simplify the LLDB website structure

Feedback I hear regularly is that the LLDB website is hard to navigate.
This patch is an attempt to simplify things by breaking the website up
in 3 major areas: "Using LLDB", "Scripting LLDB" and "Developing LLDB".

  - The majority of the "project" pages were eliminated. The projects
    page was moved under "Developing LLDB". The releases page was
    replaced with a link under "External links". The other pages (goals,
    features and status) were pretty outdated and while they probably
    made sense in the past, they don't feel all that relevant anymore
    now that LLDB is an established debugger.

  - "USE & EXTENSION" was renamed to "Using LLDB". Besides that, this
    section remained mostly unchanged. The exception are the Python
    pages which were moved under "Scripting LLDB".

  - "Development" was renamed to "Developing LLDB" and now houses all the
    resources for LLDB developers. The old "Design" section (which only
    contained two pages) was moved back under here too.
