[WellSQL Migration] Migrate WCGlobalAttributeModel to Room

[ParaskP7]

Closes: AINFRA-552
Relates To: #14453

---

Description

This PR migrates WCGlobalAttributeModel from WellSQL to Room database.

FYI: This is a follow-up to #14453 and the removal of WCAttributeTermModel. This follow-up also removes the termsId column from the WCGlobalAttributeModel table before the actual migration starts (6e07007).

I actually lost more time trying to connect the dots rather than migrating/removing this table... 😭

I now have a hypothesis about whether this WCAttributeTermModel table, the termsId column from the WCGlobalAttributeModel table, and all the unnecessary logic within the corresponding Store/Rest/SQL classes (which btw, now got removed: 2f1b0e7). My hypothesis is, as part of this FluxC#1803 PR, especially after seeing this commit, Thomaz made all attribute related CRUD operations available no matter if there were to be used (or not). Most probably the plan was to use them at some point, but, that never actually happened. Thus, all this logic ended-up being unused, and at best only used within FluxC's example app.

Testing information

1. Go to the Products screen.
2. Find a Variable product or change a Physical product to a Variable product.
3. Click on Add variations to navigate to the Add attribute screen.
4. Tap to select an existing attribute (like Color or Size) and see the list of option of that attribute.
5. Tap on a couple of options and then click NEXT twice, then press the GENERATE VARIATION button and select Generate all variations, following by OK when the dialog appears.
6. Click on Add variations again to navigate to the Variations screen where you'll see the variations you added.
7. Go back and click the SAVE button to have these changes apply to the product.

EXTRA

You might also want to add a new attribute on your store and see that everything is working as expected. To do so, follow the below instructions:

1. Go to your store's wp-admin.
2. Find the Products section, and within it, click on the Attributes sub-section.
3. Add a new attribute, following the instructions. For example, you could add a new attribute named Material with the the-material-of-the-product slug.
4. Click on Configure terms for that newly added attributed on that table, and then add a few terms for that attribute, following the instructions. For example, you could add a new term named Cotton with the cotton-product-material slug, etc. Add a few of those.
5. Now, open the mobile app and follow the above instructions once more. Making sure that this newly added attribute, along with all its terms are shown and usable.

Haha 🤣 , no worries at all. I'm adding it to my todo list, but since I was AFK yesterday, there is quite a lot there. I'll review it by the end of tomorrow the latest.

I bet @malinajirka , hoping all is good! 🫂

I'll review it by the end of tomorrow the latest.

This is not urgent, not at all, please review it when you get some extra space to breath... 🙏

Thanks @ParaskP7! Great job, I've reviewed the code and tested the changes.

I've encountered a small issue one time, but it's very likely unrelated to these changes and I haven't been able to reproduce it since. When I created a new variable product and added 3 attributes, the generate variations button would tell me there are no attributes to generate the combinations from. However, when I left that screen and entered it again, I could generate them without issues. I tried to replicate it multiple times without success.

I believe this is good to merge . Leaving it open in case the above steps would give you some idea.
