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.
