Test changing 1100D build to use RscMgr pool

[reticulatedpines]

1100D has both low malloc pool, and Alloc Mem pool. The build sizes, even for a cut down build, push up against these limits. https://docs.google.com/spreadsheets/d/1z697VRNhLzYscyTh0h9pptz9WodzQzoFG_5bWUJ_TTE/edit#gid=2

boot-d45-ch.c can target RscMgr pool, which is large (see RSCMGR_MEMORY_PATCH_END). Will need testing to see if putting ML there conflicts with the high-water mark for DryOS usage. But it appears to have worked with other cams in the past.
