Prior to this commit, parallel invocations of
MethodParameter.findParameterIndex() (invoked indirectly via
SynthesizingMethodParameter.forParameter() and
MethodParameter.forParameter()) could intermittently lead to an
IllegalArgumentException being thrown due to a race condition in the
internal implementation of the JDK's
java.lang.reflect.Executable.getParameters() method.
This commit addresses this issue by introducing a fallback for-loop
that iterates over the candidate parameters a second time using
equality checks instead of identity checks.

Prior to this commit, parallel execution of @BeforeEach and @AfterEach
methods that accepted @Autowired arguments would fail intermittently
due to a race condition in the internal implementation of the JDK's
java.lang.reflect.Executable.getParameters() method.
This commit addresses this issue by creating instances of
SynthesizingMethodParameter via
SynthesizingMethodParameter.forExecutable(Executable, int) instead of
SynthesizingMethodParameter.forParameter(Parameter), since the latter
looks up the parameter index by iterating over the array returned by
Executable.getParameters() (which is not thread-safe).

This commit introduces a new readMessageSize(DataBuffer input) private
method, inspired from CodedInputStream#readRawVarint32(int, InputStream)
and adapted for DataBuffer using MessageDecoderFunction fields in
order to support use cases where the message size is split between
distinct chunks.
It also fixes handling of end of streams by using
DataBuffer#readableByteCount instead of -1 which is only relevant with
InputStream.

Prior to this commit, when errors happened before the response was
committed, the `Content-Length` response header would be left as is.
This can be problematic since the error can be handled later in the
chain and the response body changed accordingly. For example, Spring
Boot renders error pages in those cases. If the `Content-Length` is set,
HTTP clients can get confused and only consider part of the error
response body.
This commit ensures that any `Content-Length` response header is removed
in case of errors, if the response is not already committed.
This is done at the `AbstractServerHttpResponse` level, since errors can
be handled in multiple places and the response itself is the safest
place to handle this case.
As a consequence, this commit also removes `Content-Length` checks in
`EncoderHttpMessageWriter` since we now consider that we should rely on
the response body we're about to write rather than any previously set
value.
