Michael Achenbach ee1db48cc3 Revert "[inspector] moved var initialization break location before init expression"
This reverts commit 7a9cc70492.

Reason for revert: Changes layout tests:
https://build.chromium.org/p/client.v8.fyi/builders/V8-Blink%20Linux%2064/builds/15882

This is about:
inspector/sources/debugger/source-frame-inline-breakpoint-decorations.html

Original change's description:
> [inspector] moved var initialization break location before init expression
> 
> This CL improves break locations for expressions like 'var a = <expr>'. Without CL we use <expr> position as break location for initialization statement, with this CL we use position of first character after '=' as position.
> Benefits (see test for details):
> - only one break in expressions which includes mix of property lookup and calls, e.g. var p = Promise.resolve().then(x => x * 2),
> - removed redundant break location for expressions like: let { x, y } = { x: 1, y: 2}.
>
