For tomcat, if an SslStoreProvider is configured,
`SslStoreProviderUrlStreamHandlerFactory` stores the keyStore with an
empty password. Previously, if a password was supplied using the
ssl.key-store-password property, that would be the password used to
load the keystore and the connector would fail with a
"Password verification failed" exception.

Since https://jira.spring.io/browse/SPR-16624, the contract for
`ContentNegotiationStrategy` has been refined and should never return an
empty list if it's got no preference for a media type, but it should
rather respond with a `"*/*"` instead.

This commit fixes the `OptionalPathExtensionContentNegotiationStrategy`
defined in the Spring MVC auto-configuration to have that behavior.

This commit includes some refactoring of active profiles
processing. Previously, there was a LIFO Queue for adding active
profiles. Profiles that were added last, were processed first.
Because of this reverse ordering, profiles were prepended to the
environment to preserve the order in which they were logged.
This however didn't work for "included" profiles as they were
prepended to the environment even though they were processed after
the active profile. In this commit, profiles are processed in a FIFO manner
and processed as they're found.

Fixes gh-11380
