Macro-ify access to pauseCtx->playerSegment regions (#2693)

Browse Source 
* Macro-ify access to pauseCtx->playerSegment regions.

Using macros to indicate which region in the player segment is being
accessed makes the memory layout more obvious and indicates the
intended level of memory ownership, particularly in the case of the
texture image at the start of the segment.

* Add clarifications for gameplay_keep details

* Uniform macro name for the render texture

* Comment
