Aliases for 1.20

[TheLimeGlass]

Aliases for 1.20, optimized for the easiest understanding and most flexibility.

Each item individually tested and ensured for picking understand-ability like how any wall sign should equal any normal wall sign and any wall hanging sign.

Notes

• that mangrove cannot be a tree type because it's saplings are named different and bamboo cannot be a tree type because it has no logs.
• bamboo has MOZAIC as a different block in the set.
• Moved stair variation properties to the globalvariation file for proper usage.

Before merging me might wanna wait till 1.20.2, as barriers were given a waterlogged state, which this hopefully won't be too long till then
