tracking: remove use of TypeScript enums

[iuioiua]

The main reason is that objects align more with native JavaScript than enums. There are also other technical reasons for objects being more desirable over enums. Union types may also work, depending on the scenario.

Enums show up in the following spots:

• assert/_diff.ts
• console/_tools/generate_data.ts
• datetime/week_of_year.ts
• fmt/printf.ts
• fs/eol.ts
• http/http_status.ts and http/status.ts (see BREAKING(http): deprecate enum Status in favour of STATUS_CODES object #3781)
• jsonc/parse.ts
• log/levels.ts
• toml/stringify.ts

Note: the enums in front_matter/_format.ts and archive/_common.ts are deliberately omitted as the corresponding implementations will soon be deprecated.

Has this been fixed? if not, can I fix it.

[iuioiua]

Great! Yep, it's still available. Would you like me to assign you?

[Nkiriobasi]

Yes

hi, is this is still open? (Seems to be without assignee). Could I take a stab at this?

Would it be possible to convert the tasks into individual issues or would you prefer to just reference the tracking issue in the individual prs?

[iuioiua]

Best that we tackle them in separate PRs and reference this issue.

[realpha]

@iuioiua They are all in progress now.

Thank you for completing these, @realpha. The help is very much appreciated.
