Use the checkpoint operator at various places in WebFlux to insert
information that Reactor then uses to enrich exceptions, via suppressed
exceptions, when error signals flow through the operator.

In line with the general trend toward favoring core JDK APIs for common
tasks in Spring Framework 5.2, this commit replaces handcrafted
statements with Math.min() and Math.max() were applicable.
Prior to this commit, calls to `MimeType` and `MediaType` would create a
significant amount of garbage:
* during startup time, in the static sections of `MimeType` and
`MediaType` when creating well-known types
* at runtime, when parsing media types for content negotiation or
writing known media types as strings in HTTP response headers
This commit does the following:
* Avoid parsing the well-known types and use regular constructors
instead
* Cache types in a simple LRU cache once they've been parsed, since an
application is likely to deal with a limited set of types
* Avoid using `java.util.stream.Stream` in hot code paths
Benchmarks show that a complete revision of the `MimeTypeUtils` parser
is not required, since the LRU cache is enough there.
Closes gh-22340
This commit improves the message for HttpStatusCodeException so that it
defaults to the HttpStatus reason phrase if a status text is not
provided.
This commit also fixes SimpleClientHttpResponse so that it does not
return null for getStatusText().

Commit #93b7a4 added support for pre-configuring URI variables at the
UriComponentsBuilder level, and also changed toUriString to encode
template and URI variables separately. However this went a bit too far
causing side effects for URLs with curly braces that don't represent
URI variables.
This commit restores the original toUriString behavior which is to
encode template and URI variables sepraately only if URI variables have
been pre-configured.
