Add missing variable names to PHPDoc @param of methods

Summary:
Add variable names (`$varname` in `@param type $varname explanation`) to PHPDoc method headers, for fun and profit.

Closes T15923

Test Plan:
* Read the method signatures and their corresponding PHPDoc headers at your fireplace
* Still run `./bin/diviner generate` without explosions (though it is very lenient anyway?)
