std_detect: support detecting more features on aarch64 Windows

Wire IsProcessorFeaturePresent for the PF_ARM_* constants exposed in
Windows SDK 26100 (Win11 24H2):

  fp16   PF_ARM_V82_FP16_INSTRUCTIONS_AVAILABLE  (67)
  i8mm   PF_ARM_V82_I8MM_INSTRUCTIONS_AVAILABLE  (66)
  bf16   PF_ARM_V86_BF16_INSTRUCTIONS_AVAILABLE  (68)
  sha3   PF_ARM_SHA3 (64) AND PF_ARM_SHA512 (65)
  lse2   PF_ARM_LSE2_AVAILABLE                   (62)
  f32mm  PF_ARM_SVE_F32MM_INSTRUCTIONS_AVAILABLE (58)
  f64mm  PF_ARM_SVE_F64MM_INSTRUCTIONS_AVAILABLE (59)

Also derive `rdm` from FEAT_DotProd. There is no PF_ARM_RDM_* constant;
FEAT_DotProd is an optional v8.2-A feature only present on cores that
implement at least v8.1-A, and v8.1-A with AdvSIMD mandates FEAT_RDM
(Arm ARM K.a §D17.2.91). AdvSIMD is universal on Windows-on-ARM. See
PR description for full rationale and .NET 10 precedent.

All eight feature names have been stable in `is_aarch64_feature_detected!`
on Linux/Darwin/BSD since Rust 1.60.
