fix: poll only popular network (#12658)

<!--
Please submit this PR as a draft initially.
Do not mark it as "Ready for review" until the template has been
completely filled out, and PR status checks have passed at least once.
-->

## **Description**
To reduce the impact of showing assets across all networks, which can be
unbounded, this PR scopes the portfolio view to the 9 popular networks
built into metamask.

<!--
Write a short description of the changes included in this pull request,
also include relevant motivation and context. Have in mind the following
questions:
1. What is the reason for the change?
2. What is the improvement/solution?
-->

## **Related issues**

Fixes: MetaMask/metamask-extension#29055

## **Manual testing steps**

1. On popular networks:
- The token filter should allow switching between popular networks and
current network
  - The filter should work as described
  - RPC requests in the background should only hit the popular networks

2. On other networks
- The token filter should become disabled and scoped to the current
network
  - RPC requests in the background should only hit the current network
