[jdk17u-dev] RFR: 8346671: java/nio/file/Files/probeContentType/Basic.java fails on Windows 2025

[Goetz Lindenmaier]

I backport this because we see problems on our Windows Server 2025 test machines.

I had to resolve.
StaticProperty.osName() is not in 17.
Also, two changes are missing in 17:

[8287237: (fs) Files.probeContentType returns null if filename contains hash mark on Linux](https://github.com/openjdk/jdk/commit/8071b2311caaacd714d74f12aee6cb7c2fe700fa)
[8297609: Add application/wasm MIME type for wasm file extension](https://github.com/openjdk/jdk/commit/914ef07fed960f940e1591318b9f00938b37bf09)

I don't think these should be backported as prereq.
