bug: Material design implementation for counter display with ion-item

[sean-perkins]

Prerequisites

• I have read the Contributing Guidelines.
• I agree to follow the Code of Conduct.
• I have searched for existing issues that already report this problem, without success.

Ionic Framework Version

• v4.x
• v5.x
• v6.x

Current Behavior

The counter implementation with ion-item is incorrect with the Material Design Spec: https://material.io/components/text-fields.

Expected Behavior

The counter should have the following changes:

• Text should be formatted with a space between the counts: 5 / 10 instead of 5/10 (related to feat: counterFormatter for counter string in ion-item #24327)
• Text color should be rgba(0, 0, 0, .6)
• Text letter spacing should be 0.0333333em
• The counter should always push contents to appear right-aligned
• The counter should have 16px of padding between itself and the contents to the left (in LTR)

Steps to Reproduce

Have an item implementation using v6 with the counter feature:

<ion-input [counter]="true">
   <ion-label position="stacked">Label</ion-label>
   <ion-input maxlength="20"></ion-input>
</ion-input>

Compare to the live example from the Material Design spec.
