Inline Breakpoint Support

[JustinGrote]

Prerequisites

• I have written a descriptive issue title.
• I have searched all issues to ensure it has not already been reported.

Summary

Currently PowerShell breakpoints are per-line, but they support columns as well, so we could support inline breakpoints similar to typescript, e.g. have a breakpoint specifically on hi2 but not the whole block

& {"hi";"hi2";"hi3"}

Proposed Design

Wire up the debug setBreakpoint to include column information and tie that to Set-PsBreakpoint -Column.

This should wait until #4065 lands.
