  [iOS] Several editing-related layout tests are flaky on x86_64 simulator
https://bugs.webkit.org/show_bug.cgi?id=276101
rdar://130607129

Reviewed by Megan Gardner.

For reasons that are still unknown, keyboard autocorrection triggers very 
aggressively on selection
changes when both of the following conditions are true:

1. Running tests in iOS simulator on an Intel (x86_64) host machine.
2. The iOS simulator was newly created (e.g. using `xcrun simctl create`).

This causes the following two tests to fail…

• editing/selection/ios/change-selection-by-tapping.html

    This test fails because `can't` is autocorrected to `can’t` (with an 
apostrophe instead of a
    straight quote), leading to a text diff.

• editing/selection/ios/show-grammar-replacements-on-tap.html

    This test fails because `thing` is "autocorrected" to `thing` immediately 
upon tapping to change
    the selection, which triggers an editing command that clears the grammar 
markers underneath the
    word.

• fast/events/ios/key-command-delete-to-end-of-paragraph.html

    It's actually unclear why this test is failing, due to the fact that I was 
unable to reproduce
    this at all in any configuration.

Keep these tests passing by making a couple of minor adjustments:

* LayoutTests/editing/selection/ios/change-selection-by-tapping.html:
* LayoutTests/fast/events/ios/key-command-delete-to-end-of-paragraph.html:

Force `spellcheck="false"` here to prevent correction from triggering when 
simulating selection
changes.

* Source/WebKit/WebProcess/WebPage/ios/WebPageIOS.mm:
(WebKit::WebPage::applyAutocorrectionInternal):

Return early if the original and new strings are identical, to prevent editing 
commands from
triggering (which blow away the grammar markers in 
`show-grammar-replacements-on-tap.html`).
