refactor(transformer/styled-components): use Atom everywhere

[overlookmotel]

Pure refactor. Instead of using a mix of Atom<'a> and &'a str in different places, use Atom<'a> everywhere for consistency.

block_name is only used in alloc_concat_strs_array, which only accepts &str, so I think storing Atom for block_name is unnecessary?

Anyway, I am going to merge this.

Atom<'a> is just a no-op wrapper around &'a str, so it makes no difference at all to the compiler - there's zero overhead to using Atom. I just thought in this case it was preferable to use Atom everywhere for consistency, rather than some methods using Atom<'a>, and some using &'a str.
