Revert "[vm] Recognize int.trailingZeroBitCount/oneBitCount as graph-inlinable"

This reverts commit 0bef837817.

Reason for revert: simarm, xarm bot failures https://github.com/dart-lang/sdk/issues/63436

Original change's description:
> [vm] Recognize int.trailingZeroBitCount/oneBitCount as graph-inlinable
>
> Stacks on top of the int.{trailingZeroBitCount,oneBitCount} API CL
> (commit 754239b077). Both getters route through OTHER_RECOGNIZED_LIST
> when a hardware fast path is available; otherwise the newly added
> Dart bodies inline at call sites via vm:prefer-inline. The C++
> natives are removed.

> ARM64:     NEON CNT + UADDLV (popcount); RBIT + CLZ (ctz).
> ARM:       NEON CNT + VPADDL chain (popcount); RBIT + CLZ on the
>            register pair (ctz).
> x64:       popcntq when TargetCPUFeatures::popcnt_supported();
>            LoadImmediate(64) + rep_bsfq for ctz (decodes as tzcnt
>            on BMI1+, preserves dest on zero otherwise).
> RISC-V 64: cpop / ctz when RV_baseline includes Zbb.
>
> Per-arch availability is encapsulated in
> UnaryInt64OpInstr::IsSupported(Token::Kind).
