chore(bl): add UNALIGNED symbols for TEXT/RODATA

Add symbols to mark end of TEXT/RODATA before page alignment.
Similar change was done by commit 8d69a03f6a7d ("Various
improvements/cleanups on the linker scripts") for
RO_END/COHERENT_RAM. These symbols help to know how much free
space is in the final binary because of page alignment.

Also show all *UNALIGNED__ symbols via poetry.
For example:
poetry run memory -p zynqmp -b debug
