feat: bip 44 network selector

[salimtb]

Description

BIP-44: introduce the unified network selector scoped to an account group (EVM + Solana, BTC later) with support for popular and custom networks, CAIP-19 display, and parity with existing feature flags.

Why
• BIP-44 groups multiple accounts under one “account group.” Users need a single selector that reflects all enabled networks for that group instead of EVM-only.

core PR: MetaMask/core#6499

Changelog

CHANGELOG entry: Added a unified network selector for BIP-44 account groups, showing EVM and Solana networks in one place and supporting custom networks.
