Another step towards having `zlog` as the default logging solution in
Zed.
The new ScopeMap replaces the previous HashMap based implementation used
for scope lookups to:
A. Reduce complexity
B. Increase speed at which non-enabled logs can be filtered out
C. Provide more granular control over how scopes are determined to be
enabled/disabled,
and what caching/other speed increase opportunities are available
