BaseTools/tools_def AARCH64 RELEASE: move GCC49/GGC5 to 4 KB alignment

Since 4 KB section alignment is required when mapping PE/COFF images
with strict permissions, update the default section alignment when
using GCC49 and GCC5 in RELEASE mode. Note that XIP modules such as
SEC, PEIMs or PEI core are not affected by this change, since the
override to 32 byte aligment remains in effect.
