fix(neoverse-rd): set correct SVE vector lengths
Affected platforms: RD-N2, RD-V1, RD-V1-MC, RD-V3 and their
configurations.
Previously, the SVE vector lengths for these platforms were
being taken from the default configuration. This commit updates
their respective platform.mk files to specify the correct vector
lengths.
