Add missing special encounters gens 3-5

[SimplyBLGDev]

• Added missing special encounters (mostly static overworld pokemon) along with corresponding missing location, location areas, and encounter conditions to support them.
• Two entries have been added to the pokemon table to support the female version of jellicent and frillish, since this alternative form wasn't in that table yet for some reason.

Missing special encounters from gens 6 and 7 are numerous and complex, may be adding them in the near future if I can get around to it.

Hi, we can this error in the CI:

UNIQUE constraint failed: pokemon_v2_encounter.id

I don't think it's releated to this file, but in this file maybe it's worth adding the trailing ,0 at lines 78-81

Also there's a small edge case I wanted to discuss:
Some of these special encounters are locked to certain forms of a pokemon (for example the male and female Jellicent encounters I added in this PR) but the way the current pokemon table is set up, alternative forms are pretty binary (we have a frillish and jellicent entry in their natdex position which default to being the male form, while the female form is in the 10000+ ID range, because it's an 'alternate form'), however the wild encounters with frillish and jellicent are gender neutral, the game rolls for gender while the encounter generates, this isn't compatible with the alternate form system since only the female form has an additional entry.
Should we add another entry for the specifically male counterpart, and leave the default entry as gender neutral? (I guess this would also apply to some other pokemon like Meowstic, Indeedee, Basculegion, and Oinkologne, don't know if you can think of another one this)
If you give me the green light I'll add them myself

Hmm, but I think that Jellicent in reality has two genders only, right? Male and female? There's no neutral I think.

So I think we encountered another limitation due to how the data is structured in our API.

It does but most encounters can result in either male or female, while some special encounters are forced into one or the other, the same can happen in other encounters (say unown)

This can be merged now
