This patch splits +sme feature into three separate features:

- `+streaming-sme`
- `+nonstreaming-compatible-sme`
- `+sme-za`

`+streaming-sme` enables SME instructions that are valid in Streaming SVE
mode (PSTATE.SM == 1).

`+nonstreaming-compatible-sme` enables SME instructions that are valid
outside of Streaming SVE mode (PSTATE.SM == 0).

`+sme-za` enables SME instructions that are valid when access to the
accumulator array has been enabled (PSTATE.ZA == 1). This feature is
orthogonal to Streaming mode (PSTATE.SM).
