refactor(transformer/styled-components): do not allocate temp data into arena

[overlookmotel]

Only strings which are part of AST should be stored in arena. Use String instead of StringBuilder for the temp string here.

Ideally we'd use a scratch allocator for temp data to avoid allocations, but we don't have that yet. oxc-project/backlog#121
