#56664: Blocks try to load non-existent block-styles on the frontend

There's a small error in the `register_block_style_handle()` function
which prevents us from properly determining if a stylesheet for a block
exists or now.
We use `$style_path_norm = wp_normalize_path( realpath( dirname(
$metadata['file'] ) . '/' . $style_path ) );` to get the stylesheet's
path, and then we check if the file exists by doing `$has_style_file =
false !== $style_path_norm;`.
The problem is that `realpath()` returns`false` if the file does not
exist, however it then passes through `wp_normalize_path()` and the
`false` value gets converted to an empty string.
