coreinfo: Add support for link time optimization

This introduces a Kconfig option for compiling coreinfo with LTO.
This option can be used independently of LTO in libpayload, though will
benefit most if that is enabled as well. If both are enabled, the
final size of coreinfo.elf is reduced from 95 KiB to 92 KiB.

Tested in QEMU and on Thinkpad T500.
