Object.getOwnPropertyDescriptors is missing from ES2017 lib d.ts

[xirzec]

TypeScript Version: 2.4.2

Code

Object.getOwnPropertyDescriptors({});

Expected behavior:

Compiles with --lib es2017

Actual behavior:

Doesn't compile, missing definitions

You can see it's missing from the lib file: https://github.com/Microsoft/TypeScript/blob/master/lib/lib.es2017.object.d.ts

Reference of the implementation:
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/getOwnPropertyDescriptors

lib\* is just the LKG that we use to bootstrap the compiler, it has not been updated in a while.

the definition for getOwnPropertyDescriptors should be in typescript@next. here is the definition https://github.com/Microsoft/TypeScript/blob/4d2aa9bf2cef463df1cfea3b206eb3f04e1ca765/src/lib/es2017.object.d.ts#L30.

this was added by #18175
