Cherry-pick "Use bottom-up ELF placement policy" - #1408

Conversation
This PR replaces the Linux shim loader's top-down fallback placement policy with a bottom-up policy. Currently, if placement of the main ELF at `DEFAULT_LOW_ADDR` fails, the loader searches downward from `TASK_ADDR_MAX` for a suitable gap without accounting for trampoline allocation or `brk`-based heap growth. Instead, this PR places the ELF in the first suitable gap at or above `DEFAULT_LOW_ADDR`. --------- Co-authored-by: Sangho Lee <sanghle@microsoft.com> (cherry picked from commit fcad93e)
