fix(L2): enable optimism token list when switched to optimism (#2036)

* add title text and opacity variability to token lists

* add optimism token list

* show tokens from active lists

* sort up token lists
with tokens on the current chain

* fix up some type issues

prune out chainId changes

* clean up leftover any

* refactor token count mechanism

* handle plurals in title text string

* new combineMaps implementation

* remove custom plural

* address a couple nits

* show the number of tokens on current chain
