Refactor container. Remove old features.

This is a moderate refactoring of the container to clean up code and
remove some legacy features that haven’t been documented in several
years. The make() method no longer accepts a second argument of
parameters - needing this feature indicates a code smell and you can
always construct the object in another way. It simply complicated the
container and code and made it hard to read.

Secondly, the share() method has been removed. This method was an old
method to provide backwards compatibility with Pimple. It has not been
documented in a few years and the more popular “singleton()” method is
easier to use.

Thirdly, the Normalize() method has been removed. This is the most
called method in all of Laravel and it is called almost 1,000 times on
every request because of the heavy usage of the container. On a fresh
opcache enabled run of Laravel it is actually uses about 8-9% of the
entire request processing time. It’s whole purpose is to allow you to
bind objects into the container with a leading slash; however,
Foo::class never returns a leading slash and if you pass a string we
can simply document that a leading slash should not be provided.
