[SVE] [aarch64] Add "@" in vcond_mask pattern

[Prathamesh Kulkarni]

Hi Richard,
I screwed up while committing pr88839 fix, by not including the change
to aarch64-sve.md
that adds "@" to vcond_mask pattern, which resulted in trunk failing to build
with: "gen_vcond_mask" was not declared in this scope -:/
The attached patch resolves the failure.
OK to commit ?

Thanks,
Prathamesh
