Missing alternates for eng.sc; Eng.alt2 seems redundant

[brawer]

For Noto Sans, would it make sense to add small-caps variants whose design matches Eng.alt1 and Eng.alt3? Without eng.sc.alt1 and eng.sc.alt3 (or whatever those glyphs would be called), languages that require a variant Eng (such as certain African languages) cannot be correctly displayed in small caps.

Also, should Eng.alt2 be removed? It looks like a duplicate of Eng.

According to @andjc, some languages use an n variant of Eng without descender. Currently, this variant is missing from Noto Sans. Perhaps Eng.alt2 was intended to be that variant? Not sure how it should look; perhaps like this?

Looking at this again:

• Eng.alt2 does appear to be redundant.
• Yes, eng.sc should have alternate forms as well.
• Eng.alt1/alt3 could do with locl rules to select them in appropriate languages. Neil Patel suggests that lug would be one language that needs it.
• It would probably also be wise to have a stylistic set for Eng selection as well.
