 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.

 Props mukesh27, joemcgill, daxelrod, tabrisrp.
 Fixes #59178.
