Crypto identity reset

[stefanceriu]

Add support for resetting the user's crypto identity. This is to be used when the user cannot verify their device and no longer has access (or configured) their recovery key.
It will go through the steps of

• deleting existing backups
• disabling recovery
• requesting authorization (password or OIDC/MAS) and resetting crossigning
• re-enabling backups (if allowed)

On the app side this will most likely be invoked from the onboarding screens and, on successul reset, it will continue with the rest of the onboarding flows as normal.

Requires matrix-org/matrix-rust-sdk#3759 and matrix-org/matrix-rust-sdk#3790

Legacy:

OIDC:

Nice, looks good to me. I think it would be nicer if we had a flow coordinator for all this, but not essential. That way we could add the flow (at least with a password) to the UI tests so we know it still works.
