Editor: Optimize wp_get_block_css_selector to remove array_merge calls for better performance.

Some block themes like TT3 use wp_get_block_css_selector to determine a CSS selector based on block type and other parameters. However, recent performance profiling indicated a bottleneck in wp_get_block_css_selector, particularly sections that utilize array_merge. By slightly refactoring these sections, array_merge calls can be avoided which increases performance.

Fixes #59178.
