[clang-tidy] Move clang-tidy docs to a separate directory. Create doc files for checks

The doc files for checks have been generated from the corresponding header files
using the docs/clang-tidy/tools/dump_check_docs.py script. Committing the script
as well, but the intention is to move all the user-facing docs from header files
to the rST files and add links to .h files appropriately.

+misc-noexcept-move-constructor
+==============================
+
+
+The check flags user-defined move constructors and assignment operators not
+marked with ``noexcept`` or marked with ``noexcept(expr)`` where ``expr``
+evaluates to ``false`` (but is not a ``false`` literal itself).
+
+Move constructors of all the types used with STL containers, for example,
+need to be declared ``noexcept``. Otherwise STL will choose copy constructors
+instead. The same is valid for move assignment operations.
