## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->
The `ion-input` component currently specifies a `size` attribute to
align with the HTML `input` implementation. However, Ionic's custom
appearance for MD and iOS is not compatible and should not be used with
the `size` attribute:
https://github.com/ionic-team/ionic-framework/issues/27945#issuecomment-1669702274.
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
- The `size` property has been removed from `ion-input`.
## Does this introduce a breaking change?
- [x] Yes
- [ ] No
<!--
If this introduces a breaking change:
1. Describe the impact and migration path for existing applications
below.
2. Update the BREAKING.md file with the breaking change.
3. Add "BREAKING CHANGE: [...]" to the commit description when merging.

for more information.

The `size` attribute has been removed from `ion-input`. As it was not
compatible before, this is likely to have a minimal impact to
developers. If your application is using the `size` attribute, replace
the usage with CSS styling to control the width of the `ion-input`.
