[SPARK-34151][SQL] Replaces java.io.File.toURL with java.io.File.toURI.toURL

[LuciferYang]

What changes were proposed in this pull request?

java.io.FIle.toURL method does not automatically escape characters that are illegal in URLs.

Java doc recommended that new code convert an abstract pathname into a URL by first converting it into a URI, via the toURI method, and then converting the URI into a URL via the URI.toURL method.

So this pr cleaned up the relevant cases in Spark code.

Why are the changes needed?

Cleaning up @Deprecated Java API usage.

Does this PR introduce any user-facing change?

No

@HyukjinKwon Let me check it again

Lines 1358 to 1372 in 78893b8

	private def getExtractPartFunc(partToExtract: UTF8String): URI => String = {
	// partToExtract match {
	// case HOST => _.toURL().getHost
	// case PATH => _.toURL().getPath
	// case QUERY => _.toURL().getQuery
	// case REF => _.toURL().getRef
	// case PROTOCOL => _.toURL().getProtocol
	// case FILE => _.toURL().getFile
	// case AUTHORITY => _.toURL().getAuthority
	// case USERINFO => _.toURL().getUserInfo
	// case _ => (url: URI) => null
	// }
	partToExtract match {

@HyukjinKwon The rest is as above. I don't know if this part of code is still useful.

EDIT: seems _ is URI.

Yes
