pgsql: Refactor heap_page_prune_and_freeze() parameters into a struct

Refactor heap_page_prune_and_freeze() parameters into a struct

heap_page_prune_and_freeze() had accumulated an unwieldy number of input
parameters and upcoming work to handle VM updates in this function will
add even more.

Introduce a new PruneFreezeParams struct to group the function’s input
parameters, improving readability and maintainability.
