Subject: [PATCH] fix: safari no longer adjusts text in landscape (#27787)

Issue number: resolves #27782

<!-- Please do not submit updates to dependencies unless it fixes an
issue. -->

<!-- Please try to limit your pull request to one type (bugfix, feature,
etc). Submit multiple pull requests if needed. -->

## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->

Ionic uses text-size-adjust to prevent browsers from resizing text in
landscape mode in order to match native app behavior. However, WebKit
only supports `-webkit-text-size-adjust`, so this fix never applied to
iOS devices.

https://caniuse.com/?search=text-size-adjust

## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->

- Add `-webkit-text-size-adjust` where we use `text-size-adjust`

## Does this introduce a breaking change?

- [ ] Yes
- [x] No

<!-- If this introduces a breaking change, please describe the impact
and migration path for existing applications below. -->
