  [AArch64][GISel] Translate legal SVE formal arguments and select COPY for SVE (#95236)

This patch adds support for legal SVE fromal arguments in IRTranslator,
and support for COPY with SVE.

SVE arguments are allowed only if the hidden option
`-aarch64-enable-gisel-sve` is enabled. Illegal types and predicates
like `nxv8i1` are not supported yet.
