o/build/mkpayload: port to llvm-objcopy

GNU and LLVM objcopy have some material differences in how they work.
LLVM is able to automatically assign VMAs, but needs --set-section-flags
for it. Use that and drop all the explicit VMAs.
Also with the new toolchain cc.objcopy_excutable is not populated, so we
need to get the executable path using the new action-based way.

Currently contains a hack to force static on to get our custom toolchain
for both host and cross-builds as GNU objcopy is not compatible.
