Place .xip sections into flash

We added the `.xip` section to ensure that the reset handler and
pre-init functions would be placed in flash. This commit lets users
place other content into that section.

`.xip` is intended for instructions. The runtime builder will place
these instructions into the same load region as `.text`. However,
there's no pre-`main` relocation.

Aligning the `.xip` and the `.text` section produces more predictable
behavior between GNU's ld and LLVM's lld.
