Add PortalBase and Fake Requests and update Frozen Libs on Portal boards

[makermelissa]

This will free up some memory on a few of the boards that use the PortalBase library, which currently does not function on the MatrixPortal and is pretty close to the max space on the others.

Hmm, it's failing with this error:

Nope, it's this error actually:

I probably froze it wrong.

Make sure that the submodule is pointed exactly at a tagged release, not at the tip of main.

I don't think I did that. How is that done?

[makermelissa]

I went into the submodule and checked out the release tag for each and then committed for this PR. Hopefully that's right.

@makermelissa If you go to the top level at circuitpython/, there is a make target: make update-frozen-libraries, which does this for you. It will update all that need updating.

It's too much for poor matrixportal to handle .. by a lot 😢

/usr/bin/../lib/gcc/arm-none-eabi/10.2.1/../../../../arm-none-eabi/bin/ld: build-matrixportal_m4/firmware.elf section `.text' will not fit in region `FLASH_FIRMWARE'
/usr/bin/../lib/gcc/arm-none-eabi/10.2.1/../../../../arm-none-eabi/bin/ld: region `FLASH_FIRMWARE' overflowed by 33872 bytes

[makermelissa]

Ok, hmm. Now to figure out what to leave out. I did give it everything relevant to it.

[makermelissa]

I removed DisplayText from MatrixPortal since it really contains 3 variations and only one is loaded in memory, but it uses 60k of frozen space.

[makermelissa]

I tested compiling locally and it was still failing, so I removed a couple more frozen libs and disabled some modules that likely aren't used such as sharpdisplay, sdcardio, and bleio. If any of those are actually needed for the MatrixPortal, we can shuffle it around some more.

[jepler]

Don't portal boards have SD card slots? It'd be nice to put back sdcardio. Oh, that applied only to matrixportal, which doesn't have an SD slot.

Is the inclusion of FakeRequests unavoidable? well, I guess it's not very big...

Correct.

Yeah, it's more of a convenience thing. We could remove it if you think that's be better.

[dhalbert]

Looks good! It's too bad we have to do this even on these big chips, but there's a lot of code.

Agreed, I think optimizing the portal libraries would help. I have an issue open to do that.
