MM snaps multi-account support

[gomesalexandre]

Overview

Currently, snaps do not support multi-accounts.

That is reflected in two ways:

• First, the "Add Account" button doesn't show in wallet
• Second, the autofetching of accounts 0+ isn't made for MM with snaps

Both of these are caused by supportsBip44Accounts being false for MM with the hdwallet multichain adapter.

References and additional details

Grep for supportsBip44Accounts across hdwallet multichain and web.

Acceptance Criteria

Either:

• supportsBip44Accounts is updated in the multichain hdwallet adapter to notify multi-account support (preferred) or
• web consumption is monkey-patched to true when snap is installed
• We don't try and fetch accounts 0+ for EVM accounts, since that's not supported by snaps
