  [Clang][AArch64] Fix checkArmStreamingBuiltin for 'sve-b16b16' (#109420)

The implementation made the assumption that any feature starting with
"sve" meant that this was an SVE feature. This is not the case for
"sve-b16b16", as this is a feature that applies to both SVE and SME.

This meant that:
```
  __attribute__((target("+sme2,+sve2,+sve-b16b16")))
  svbfloat16_t foo(svbfloat16_t a, svbfloat16_t b, svbfloat16_t c)
                                                      __arm_streaming {
      return svclamp_bf16(a, b, c);
  }
```
would result in an incorrect diagnostic saying that `svclamp_bf16` could
only be used in non-streaming functions.
