RFR: 8352728: InternalError loading java.security due to Windows parent folder permissions [v2]

[Francisco Ferrari Bihurriet]

> Hi, this is a proposal to fix 8352728.
> 
> The main idea is to replace [`java.nio.file.Path::toRealPath`](https://docs.oracle.com/en/java/javase/24/docs/api/java.base/java/nio/file/Path.html#toRealPath(java.nio.file.LinkOption...)) by [`java.io.File::getCanonicalPath`](https://docs.oracle.com/en/java/javase/24/docs/api/java.base/java/io/File.html#getCanonicalPath()) for path canonicalization purposes. The rationale behind this decision is the following:
> 
> 1. In _Windows_, `File::getCanonicalPath` handles restricted permissions in parent directories. Contrarily, `Path::toRealPath` fails with `AccessDeniedException`.
> 2. In _Linux_, `File::getCanonicalPath` handles non-regular files (e.g. `/dev/stdin`). Contrarily, `Path::toRealPath` fails with `NoSuchFileException`.
> 
> #### Windows Case
> 
> @martinuy and I tracked down the `File::getCanonicalPath` vs `Path::toRealPath` behaviour differences in _Windows_. Both methods end up calling the [`FindFirstFileW`](https://learn.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-findfirstfilew) API inside a loop for each parent directory in the path, until they include the leaf:
> 
> * [`File::getCanonicalPath`](https://github.com/openjdk/jdk/blob/jdk-24-ga/src/java.base/share/classes/java/io/File.java#L618 "src/java.base/share/classes/java/io/File.java:618") goes through the following stack into `FindFirstFileW`:
>     * [`WinNTFileSystem::canonicalize`](https://github.com/openjdk/jdk/blob/jdk-24-ga/src/java.base/windows/classes/java/io/WinNTFileSystem.java#L473 "src/java.base/windows/classes/java/io/WinNTFileSystem.java:473")
>     * [`WinNTFileSystem::canonicalize0`](https://github.com/openjdk/jdk/blob/jdk-24-ga/src/java.base/windows/native/libjava/WinNTFileSystem_md.c#L288 "src/java.base/windows/native/libjava/WinNTFileSystem_md.c:288")
>     * [`wcanonicalize`](https://github.com/openjdk/jdk/blob/jdk-24-ga/src/java.base/windows/native/libjava/canonicalize_md.c#L233 "src/java.base/windows/native/libjava/canonicalize_md.c:233") (here is the loop)
>     * If `FindFirstFileW` fails with `ERROR_ACCESS_DENIED`, `lastErrorReportable` is consulted, the error is [considered non-reportable](https://github.com/openjdk/jdk/blob/jdk-24-ga/src/java.base/windows/native/libjava/canonicalize_md.c#L139 "src/java.base/windows/native/libjava/canonicalize_md.c:139") and the iteration is stopped [here](https://github.com/openjdk/jdk/blob/jdk-24-ga/src/java.base/windows/native/libjava/canonicalize_md.c#L246-L250 "src/java.base/windows/native/libjava/c...
