[PDF OCR] Refresh PDF accessibility tree on an AXMode change

On an AXMode change, trigger LoadOrReloadAccessibility() in
PdfViewWebPlugin to rebuild the PDF accessibility tree. When receiving
an AXMode for PDF OCR, PdfOcrService will be created and used to
extract text from images. When receiving AXMode without PDF OCR flag (possibly when the user turns off PDF OCR), the PDF accessibility tree
needs to be built again without OCR results.

This CL enables ChromeVox users to navigate PDF content without
refreshing a PDF tab after turning on PDF OCR. PDF accessibility tree
will be rebuilt when the user chooses to run PDF OCR always or once
and then become available to ChromeVox.

For more information about running PDF OCR always or once, please visit
the design deck in the following go link: go/pdf-ocr-ui

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.

If you found a bug, please file it at https://crbug.com/new.
