Always replace device placeholders in DoH URI templates

Currently, if the DoH URI template contains placeholders for device
identifiers these placeholders are ignored for unaffiliated users.

This is incorrect because the template delimiters are not URL encoded
and it breaks the DoH server assumptions regarding the size of the
identifier replacement.

This CL changes the current logic by hashing and hex encoding the
value of the placeholder name for users which are not affiliated.

E.g. the replacement for ${DEVICE_ASSET_ID} is
uppercase_hex(sha256(VALUE_NOT_AVAILABLE)).

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.
