Web3: handle wallet_revokePermissions (EIP-2255)

Up through 0.3.20 wallet_revokePermissions was unhandled and fell
through to the chain-RPC relay, which returned a non-JSON error
that surfaced as 'invalid character m looking for beginning of
value' on etherscan.io.

Implement EIP-2255 revoke: params=[{<perm>:{}}]; for the only
permission libwallet grants (eth_accounts), drop every
ConnectedSite row for the requesting host (same effect as
solana_disconnect on the Solana side). Unknown permissions are
silently ignored for forward-compat (matches MetaMask).

Returns null on success.
