aarch64: Define CSRE system registers
This patch introduces CSRE (Call Stack Recorder Extension) system
registers.
Note: as this is register only extension we do not want to hide these
registers behind -march flag going forward (they should be enabled by
default).
CSRE feature adds CSR PDEC (Decrements Call stack pointer by the size
of a Call stack record) instruction. This instruction will be added in
a following, separate patch. This change only adds CSRE system
registers.
