Improve PathMatcher/PatternParser XML configuration

Prior to this commit, the MVC namespace for the XML Spring configuration
model would use the `PathMatcher` bean instance when provided like this:

```
<bean id="pathMatcher" class="org.springframework.util.AntPathMatcher"/>
<mvc:annotation-driven>
  <mvc:path-matching path-matcher="pathMatcher"/>
</mvc:annotation-driven>
<mvc:resources mapping="/resources/**" location="classpath:/static/"/>
```

With this configuration, the handler mapping for annotated controller
would use the given `AntPathMatcher` instance but the handler mapping
for resources would still use the default, which is `PathPatternParser`
since 6.0.

This commit ensures that when a custom `path-matcher` is defined, it's
consistently used for all MVC handler mappings as an alias to the
well-known bean name. This allows to use `AntPathMatcher` consistently
while working on a migration path to `PathPatternParser`

This commit also adds a new XML attribute to the path matching
configuration that makes it possible to use a custom `PathPatternParser`
instance:

```
<bean id="patternParser" class="org.springframework.web.util.pattern.PathPatternParser"/>
<mvc:annotation-driven>
  <mvc:path-matching pattern-parser="patternParser"/>
</mvc:annotation-driven>
```
