Do not preserve css text transforms for plain text copy

Following spec https://www.w3.org/TR/css-text-3/#text-transform,
the copy/paste payload from |SelectedTextForClipboard()| and
|SelectedHTMLForClipboard()| should not preserve css text transforms
for plain text.

If text node has text-transform set, |TextIteratorTextNodeHandler|'s
|ComputeTextAndOffsetsForEmission()| would get text from
LayoutText::OriginalText() which is devoid of text transforms.

This behavior is controlled with properties added in
TextIteratorBehavior and CreateMarkupOptions defaulting to ignore
text transforms for plain text copy.

Since this is a web facing change, the change is put behind a
runtime feature flag enabled by default. In case there
is an unexpected regression, the feature flag can simply
be turned off (remotely).

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure.

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
