Editor: Move variables to where used in wp_render_layout_support_flag.

Improves the performance of wp_render_layout_support_flag() function by moving variables to where each is used.
If a return happens before the variable is needed, this change avoids unnecessary processing and memory.

Props spacedmonkey, hellofromTonya, mukesh27.
Fixes #57815.
