[AArch64] Support RAS extension for ARMv8 onwards.
The RAS extension was introduced as part of the ARMv8.2 architecture
where it is a required feature. It is also available as an optional
feature for ARMv8 and ARMv8.1. In binutils, the RAS extension is
currently enabled by default for -march=armv8.2-a but is not available
for -march=armv8 or -march=armv8.1-a.
This patch adds the feature extension '+ras' to enable the RAS extension
for ARMv8 and ARMv8.1, it is disabled by default.
