Follow on to D110006, related to D110957 Where implementations have diverged this resolves to match the new DeviceRTL - replaces definitions of this struct in deviceRTL and plugins with include - changes the dynamic_shared_size field from D110006 to 32 bits - handles stdint being unavailable in DeviceRTL - adds a zero initializer for the field to amdgpu - moves the extern declaration for deviceRTL to target_interface (omptarget.h is more natural, but doesn't work due to include order with debug.h) - Renames the fields everywhere to match the LLVM format used in DeviceRTL - Makes debug_level uint32_t everywhere (previously sometimes int32_t) Reviewed By: jdoerfert Differential Revision: https://reviews.llvm.org/D111069
