[AArch64] Avoid scanning feature list for target parsing 

As discussed in https://reviews.llvm.org/D120111, this patch proposes an
alternative implementation to avoid scanning feature list for
architecture version over and over again. The insertion position for
default extensions is also captured during this single scan of the
feature list.
