Previously the CsrfToken was set on the request attribute with the name
equal to CsrfToken.getParameterName(). This didn't really make a lot of
sense because the CsrfToken.getParameterName() is intended to be used as
the HTTP parameter that the CSRF token was provided. What's more is it
meant that the CsrfToken needed to be read for every request to place it
as an HttpServletRequestAttribute. This causes unnecessary HttpSession
access which can decrease performance for applications.
This commit allows setting CsrfFilter.csrfReqeustAttributeName to
remove the dual purposing of CsrfToken.parameterName and to allow deferal
of reading the CsrfToken to prevent unnecessary HttpSession access.
Issue gh-11699
Previously LazyCsrfTokenRepository supported lazily saving the CsrfToken
which allowed for lazily saving the CsrfToken. However, it did not
support lazily reading the CsrfToken. This meant every request required
reading the CsrfToken (often the HttpSession).
This commit allows for lazily reading the CsrfToken and thus prevents
unnecessary reads to the HttpSession.

Previously loadContext(HttpServletRequest) could return a Supplier that
returned a null SecurityContext
This commit ensures that null is never returned by the Supplier by
returning SecurityContextHolder.createEmptyContext() instead.

Currently if trace logging is enabled a StackOverflowException is thrown
when trying to resolve toString of the authentication.

Issue gh-11457
Previously AnonymousAuthenticationFilter accessed the SecurityContext to
determine if anonymous authentication needed setup eagerly. Now this is done
lazily to avoid unnecessary access to the SecurityContext which in turn avoids
unnecessary HTTP Session access.

When MultipartFormData is enabled currently the CsrfWebFilter compares
the content-type header against MULTIPART_FORM_DATA MediaType which
leads to NullPointerExecption when there is no content-type header.
This commit reverse the check to compare the MULTIPART_FORM_DATA
MediaType against the content-type which contains null check and avoids
the exception.
