Input component labels in outlined mode need some work

[StefanWallin]

Current behaviour

1. When background and primary are close to each other we are not able to style text-color of labels on input-components separately from primary color in theme. It's weird that primary is used both in backgrounds and texts without escape hatches.
2. When placing a rounded <TextInput> with mode="outlined" and outlineStyle={{borderColor:'transparent'}} on a elevated <Surface>, then the backgroundColor of the label gets a weird shape.

Expected behaviour

I expect:

• The rounding of the input to hide the label background
• The label background to be styleable without creating a label element
• Each of the inputs parts to have to have escapeHatches for styling, such as these props, or a style function that takes it's state(focused, normal, disabled) labelStyle, activeLabelStyle, inputStyle, activeInputStyle,

How to reproduce?

Preview

Background is dark to show low contrast between background and primary text

Background is set to red to highlight the weird shape of the label

What have you tried so far?

Creating custom label components without getting it to work consistently across platforms (android & iOS)

@StefanWallin If we pass a Text component with a color as a label to a text input in outlined mode, it looks like this:

<TextInput.... ..... label: <Text style={{ color: '#333333' }}</Text>
