Rework fontsize, better defaults

[MV-GH]

	Compose default in SP	Jerboa default in Px	Jerboa default in SP now
headlineLarge	32	16	22*
headlineMedium	28	13	16*
headlineSmall	24	9	14*
titleLarge	22	16	22
titleMedium	16	13	16
titleSmall	14	9	14
bodyLarge	16	16	16
bodyMedium	14	13	14
bodySmall	12	9	12
labelLarge	14	16	14
labelMedium	12	13	12
labelSmall	11	9	11
displayLarge	57	x	x
displayMedium	45	x	x
displaySmall	36	x	x

I made it scale with the ratio of the bodyLarge, meaning that if you set font size to 14 bodyLarge becomes 14.
And the other styles resize at the same ratio (14/16 = 87.5% size)

Fixes #1403

I am not done yet. But I recommend checking out if you see anything standing out. I made it so that most fields stay the same.

This approach does seem much simpler, thx.

Somethings I don't get

How it looked the old way:

this is twice titleMedium somehow new has more weight??

but using the new system

titleMedium is bigger but (even when only 14 vs original 13)
Both have the same font weight

Made it look like this

The documented changes are:

• HeaderTitle
• Tabs
• PostAndCommunityContextHeader
• SimpleTopBar (Indifferent to this one was 16 now is 22, kept compose default)

Everything else should be the exact same as before

Opinions?

Just tested this, and it fixed the primary issue, and sizing works much better now. Thx!

Thx for extracting this.
