Merge Density and DensityScope. Remove ambientDensity()

1) Renamed `DensityScope` to `Density` and bring the `density` and `fontScale` `val` properties into it directly
2) Provided a concrete implementation `DensityImpl` as a private data class
3) Provided a default factory `fun Density(...): Density` that returns a `DensityImpl`
4) Removed ambientDensity() in favour of using DensityAmbient.current directly
5) Removed withDensity(density) as now we can just use with(density)

A lot of tests are affected, but the changes there are just the replacements of the usage.

Relnote: Density and DensityScope were merged into one interface. Instead of ambientDensity() you can now use DensityAmbient.current. Instead of withDensity(density) just with(density)
Test: run all tests, demo app
