Code inclusion: update URLs for main branch

No change to logic. This updates git URLs and other docs to refer to the
"main" branch ("master" was renamed). This is mostly a trivial
mechanical change, with a couple exceptions:

* It looks like some codesearch URLs use an old unsupported format for
  permalinks. I've manually updated these to use the new format with
  corrected line numbers on the "main" branch.
* I changed one GitHub link to point to the public AOSP codesearch
  instance which Google maintains.

I manually verified each of these links works as expected.

This intentionally does not convert all references to "master" because
some of these refer to Android master branch, which has not yet been
renamed.

Test: manually checked each link
