Change allocation of FontFallbackMap to on-demand

We currently allocate a FontFallbackMap to every FontSelector and
FontCache, even when it's never used. This results in a memory
regression by a HashTableArea page (128KiB) in each renderer process.

This patch fixes that by allocating on demand.

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.

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.
