The first patch removes the scheduler duplication in the linker script.
The second patch adds CONFIG_GC_SECTIONS and makes it available for all

Pipeline here:
https://gitlab.com/xen-project/people/jandryuk-amd/xen/-/pipelines/2205223331

--print-gc-sections is enabled, and ARM builds in particular show a good
bit of removal.
