Support day-parting for Brave Ads

[jsecretan]

Description

Certain ads make the most sense during certain parts of the day. For instance, it may make sense to advertise restaurant chains before lunch to maximum success.

This issue is dependent on #5023

The campaign field now has a list of day parts. If this list is empty, this can be ignored. But if there are entries in the list, any creatives under the campaign should only be eligible to show during the given times, in the timezone of the user.

Dayparting, which is described in bat-native-ads/data/resources/catalog-scheme.json is now added as a filter rule. Any existing fields with empty parting will not be filtered.

The major note for server-side devs and reviewers is that the dow field will store the C++ version of day of week as a string of integers, where 0 is Sunday and 6 is Saturday. This is done to compress the catalog size for multiple days using the same time period.

Given that there is a transition period of empty dayparts in the catalog, we will assume empty values to apply to all days of the week and at all hours

Verification passed on macos 10.15.6 x64

Tried to verified test plan from description:

• Confirm new tab pages and notifications with no dayparts still appear (verified)
• Confirm new tab pages and notifications with dayparts only appear based on the schedule (out of scope as discussed with @tmancey)
