tint color for Textfields

[mohpor]

Hi,

Material 3.x introduces a bug where the tint color of a text field will be ignored completely, because, you are changing it based on placeholder's colors (Active/Normal) in the process. It has consequences for someone who doesn't have a placeholder and want to set the tint color.

I guess the tint color explicitly set by user should override such behavior.

For now, the workaround is to set both placeholderActiveColor and placeholderNormalColor to your desired color to achieve a simple tintColor!

Update:
I guess this is not new and has been a case since Material 2 (at least)

We forceable update tintColor to a single value placeholderActiveColor.

Material/Sources/iOS/Text/TextField.swift

Lines 535 to 538 in 3e26378

	func updatePlaceholderLabelColor() {
	tintColor = placeholderActiveColor
	placeholderLabel.textColor = isEditing ? placeholderActiveColor : placeholderNormalColor
	}

I think we can set it once in didSet of placeholderActiveColor.

@DanielDahan What do you think worth updating?

@OrkhanAlikhanov I think @mohpor's point is a really good one. Maybe we only need to update both values like @mohpor mentioned when a user sets the tintColor. We still do want to use the placeholder(Active/Normal)Color functionality. Thoughts?
