fix race in global crypto provider installation using OnceLock::set

[vtjl10]

• Summary: Replace racy install_crypto logic with atomic OnceLock::set to ensure accurate success reporting under contention.
• Problem: install_crypto could return true even if another thread initialized CRYPTO first.
• Solution: Use OnceLock::set(...).is_ok(); add set to the no_std OnceLock wrapper for consistent API.
• Changes:
  • primitives: add OnceLock::set in no_std wrapper; std path delegates to std::sync::OnceLock::set
  • precompile/interface: rewrite install_crypto to return CRYPTO.set(...).is_ok()
