Exclude `FileEditor` from the `BindConverter` since it uses slightly
unusual logic to create the file. Specifically, given a value of "."
the editor will locate a `ClassPathResource` then return `getFile()`
from that resource. For back-compatibility, binding should use the
simpler conversion service logic.

Fixes gh-12163

Update `BindConverter` so that delegation to `SimpleTypeConverter` also
works with Collections and Arrays.

Prior to this commit, conversion that relied on a `PropertyEditor` would
only work for simple types. For example, "String -> Class<?>" would use
the `ClassEditor` but "String -> List<Class<?>>" would fail.

The `BindConverter` now uses a minimal `ConversionService` as an adapter
to the `SimpleTypeConverter`. This allows us to use the same delimited
string conversion logic as the `ApplicationConverter`.

Fixes gh-12166

Consistently use `StringUtils.toStringArray`, `ClassUtils.toClassArray`
or zero length when converting collections to arrays.

This commit ensures that Tomcat is the first reactive server configured
if the Tomcat dependency is on classpath.

Spring Boot chose Reactor Netty as the default for the reactive web
starter, but the Reactor Netty dependency can be used also for its HTTP
client. In case developers are adding Tomcat, Undertow or Jetty on their
classpath, we must configure those and consider Reactor Netty for the
client only.

Drop `SpringProfileDocumentMatcher` and replace it with two new
implementations that restrict when YAML documents are loaded. YAML
sections are now restricted both on the specific profile that is being
loaded, and the profiles that are currently accepted.

The `PropertySourceLoader` interface has been refined to include a
predicate that determines when a profile is accepted. The
`ConfigFileApplicationListener` simply delegates the predicate logic to
the `Environment`.
