Add LLDB website and documentation in reStructuredText for Sphinx

The current LLDB website is written in HTML which is hard to maintain.
We have quite a bit of HTML code checked in which can make it hard to
differentiate between documentation written by us and documentation
generated by a tool.

In line with the other LLVM projects, I propose generating the
documentation with Sphix. I think text/rst files provide a lower barrier
for new or casual contributors to fix or update.

This patch adds a copy of the LLDB website and documentation in
reStructuredText. It also adds a new ninja target `docs-lldb-html` when
-DLLVM_ENABLE_SPHINX:BOOL is enabled.

This is the first step in having the website and documentation being
generated from the repository, rather than having the output checked-in
under the www folder. During the hopefully short transition period,
please also update the reStructuredText files when modifying the
website.

+LLDB
+====
+
+LLDB is a next generation, high-performance debugger. It is built as a set of
+reusable components which highly leverage existing libraries in the larger LLVM
+Project, such as the Clang expression parser and LLVM disassembler.
+
+LLDB is the default debugger in Xcode on Mac OS X and supports debugging C,
+Objective-C and C++ on the desktop and iOS devices and simulator.
+
+All of the code in the LLDB project is available under the standard
+`LLVM License <http://llvm.org/docs/DeveloperPolicy.html#copyright-license-and-patents>`__,
+an open source "BSD-style" license.
