refactor(php-shim): take filesystem paths as impl AsRef<Path>

The shim's filesystem entry points took `&str` even though each one resolves
to a local path through `std::fs` or a syscall, so callers holding a `PathBuf`
had to stringify it at the call site. They now take `impl AsRef<Path>`, the
form `file_exists`, `is_dir`, `unlink` and the rest of the already-converted
set use.

`Phar`, `PharData` and `ZipArchive` keep their archive path as a `PathBuf`.
`PharData::compress` names the compressed sibling by appending the suffix to
the file name rather than formatting the path into a `String`.

Arguments PHP resolves through a stream wrapper (`fopen`, `file_put_contents`,
`include`) still take `&str`, as do the byte-string operations (`dirname`,
`basename`, `pathinfo`) and archive-internal entry names, which are `/`-joined
logical names rather than OS paths.
