v2.1: SIMD-0075: Precompile for Secp256r1 (backport of #3152)

[mergify]

Problem

There currently isn't support for signature verification of signatures on the NIST-P256 curve (primary curve used by Passkeys). Motivation and details can be found in SIMD-0075

Summary of Changes

• Adds a precompile for secp256r1 signature verification that implements the structure defined in SIMD-0075 and that abides by the rules set forth in SIMD-0152
• Adds a separate secp256r1 crate to avoid further bloat of solana_sdk
• Adds tests to check functionality of the precompile, as well as the computed curve order values
