x86/boot: Reposition trampoline data

... to separate code from data.  In particular, trampoline_realmode_entry's
write to trampoline_cpu_started clobbers the I-cache line containing
trampoline_protmode_entry, which won't be great for AP startup performance.

Reformat the comments for trampoline_gdt to reduce their volume.

No functional change.
