std.compress: Improve tests, remove reliance on openDirAbsolute

- Previously, some of the compress tests used `@src()` in combination with `dirname` and `openDirAbsolute` to read test files at runtime, which both excludes platforms that `openDirAbsolute` is not implemented for (WASI) and platforms that `SourceLocation.file` is not absolute (this was true for me locally on Windows). Instead of converting the tests to use `fs.cwd().openDir`, they have been converted to use `@embedFile` to avoid any potential problems with the runtime cwd.
- In order to use `@embedFile`, some of the `[]u8` parameters needed to be changed to `[]const u8`; none of them needed to be non-const anyway
- The tests now use `expectEqual` and `expectEqualSlices` where appropriate for better diagnostics

```
