arm/aa64: fix the size of .rela* sections
The previous commit(*) merged .rel* and .dyn* into .rodata, and this
made ld to generate the wrong size for .rela* sections that covered
other unrelated sections. When the EFI image was loaded, _relocate()
went through the unexpected data and may cause unexpected crash.
This commit moves .rel* and .dyn* out of .rodata in the ld script but
also moves the related variables, such as _evrodata, _rodata_size,
and _rodata_vsize, to the end of the new .dyn section, so that the
crafted pe-coff section header for .rodata still covers our new
.rela and .dyn sections.
