This commit refines Reactor field precomputing on native
to only compute at build-time fields in the reactor.core
package, since doing so in reactor.netty has unwanted side
effects like Epoll always disabled.

Prior to this commit, when PathMatchingResourcePatternResolver
processed a `file:` pattern (for example, `file:/app-config/**`) for a
`rootPath` that did not exist in the filesystem, the resolver attempted
to search the directory and logged a WARNING message similar to the
following when it failed to do so.

Failed to search in directory [/app-config/] for files matching pattern
[**]: java.nio.file.NoSuchFileException: /app-config/

To avoid unnecessary attempts to search a nonexistent directory,
PathMatchingResourcePatternResolver now skips searching of a nonexistent
directory and preemptively logs an INFO message similar to the
following.

Skipping search for files matching pattern [**]: directory [/app-config]
does not exist

Closes gh-31111

This commit ensures that PathMatchingResourcePatternResolver's
doFindPathMatchingFileResources() method returns a mutable Set in order
to comply with the documented contract.
