  [AArch64][Clang][NEON] Remove undefined vcmla intrinsics (#112575)

arm_neon.td currently generates the same 24 `vcmla` intrinsic prototypes
for each of the f16, f32, and f64 base types. This is incorrect, the
only valid vcmla intrinsics for the f64 base type are:
- `vcmlaq_f64`
- `vcmlaq_rot90_f64`
- `vcmlaq_rot180_f64`
- `vcmlaq_rot270_f64`

(see ACLE
https://github.com/ARM-software/acle/blob/main/neon_intrinsics/advsimd.md)

This patch removes the incorrect intrinsic prototypes.
