This migrates the JS builtin's string type to the `<T>` type parameter
for a few more cases. This was done to eliminate null checks, casts and
dynamic calls when dartdevk builds the SDK, so it matches dartdevc.

Eliminate numerous type checks not needed in strong mode. Use
private nullability annotations instead of inline JS to mark known
non-null variables, and to make the compiler generate null checks
for null checked variables. Use nullability annotations and code refactoring to
remove redundant null checks and to move checks out of loops.

it's all under input_sdk now:
lib -> the lib folder
private -> the dart:_* libs
patch -> the files with @patch
I imagine we'll try and focus changes on the last two
