8258246: sun.net.www.ParseUtil.decode throws java.lang.IllegalArgumentException: Error decoding percent encoded characters

[fmeum]

URLClassPath called into ParseUtil.fileToEncodedURL, which misencoded characters with a four byte UTF-8 representation. Replacing that function with toPath().toUri().toURL() (and removing it, since its only used once) results in correct encoding for all Unicode characters.

@jaikiran This is my attempt at making progress on https://mail.openjdk.org/pipermail/core-libs-dev/2024-November/135869.html without touching general URL/URI encoding code. I hope that this can fix the issue while avoiding backwards compatibility concerns.
