davidbaumwald 8bd5d74be2 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.
