Script / Script Extensions cleanup

Normally, characters are given the Script property value Inherited if they are GC=Mark, and would otherwise be Common. There are a few outliers listed below.

I propose the following changes:

Common

A. U+1CE1,F2,F3 be changed to sc=Deva. If we know now that it is commonly used with other Indic scripts, or we get that information later, we can change to sc=Inherited & scx={Deva Gujr Guru Kthi Takr} (or whatever that list would be).

B. U+1D165,66,6D-6F,70-72 be changed to sc=Inherited. While these are special cases, there isn't any good reason for them to be Common instead of Inherited.

Inherited

For all of the following, if we know that it is used with any other scripts, we can add them now or later.

C. U+0342-45, U+1DC0,C1 be changed to sc=Greek.

D. U+0363-6F be changed to sc=Latn

E. U+0485,86 be changed to sc=Cyrillic

F. U+065F be changed to sc=Arabic

G. U+0951,52 be changed to sc=Devanagari

H. U+1CD0-D2, D4-DF, E0, E2-E8, ED, F4 be handled as in A.

gc=Format

I. U+06DD be changed to sc=Arabic
