Add more information to DevDiagnostics resource usage page

[xhan65]

Summary of the pull request

Extend DevDiagnostics's resource usage page to have both system resource usage information and Application resource information.

• Add a System tab and Application tab to resource usage page so user can switch between tabs to get detailed information. Application tab only appears when DevDiagnostics is attached to a process.
• In System tab, add detailed hardware and sensor information using LibreHardwareMonitorLib APIs. The hardware and sensor information are visualized via an expandable Treeview.

Perhaps define all these magic numbers as consts somewhere? #Resolved

Is this always going to be big enough, if the user has text size set to >100%? #Resolved

[xhan65]

That's a good point. No it won't be big enough if the text size gets bigger. Is there a recommended way to set the width? I noticed that with text size increased, the column for current "cpu usage", "memory usage" is not big enough either

[andreww-msft]

Well, we could adjust the width dynamically using UISettings.TextScaleFactor as a multiplier - but that seems overkill. Alternatively, set TextWrapping=wrap, but that might look odd. Simplest would be to simply pick a much bigger width (say 300?), as we have lots of horizontal real estate to play with - not perfect, but likely would cover most cases.

Please can you clarify:

1. When are the sensor values updated - all the time, or only when the (System/Application) tab is open? or only when a specific item in the tree is actually visible?
2. How frequently are they updated?
   ... can we get a summary of the behavior added to the tooltip for the page header? #Resolved

Have you validated that the resource usage is read by narrator, as well as the tabsd at the top? #Resolved

[xhan65]

Stale code, will clean #Resolved

1. Sensor values are updated when the user is in Resource usage page (both system and application tab). When user navigated away from that page, the timer is stopped.
2. Sensor values are updated every 2 seconds.

Added tooltip information to page header.

Narrator recognizes resource usage and treeview, but it wasn't able to read the tabs. I filed this bug to track the tab header accessibility issue.: #3766 I'll fix it in the next PR.

it might be as simple as adding an x:uid and something like the following to the resources.resw

Thanks! I was having trouble having narrator read the header text block, but after adding uid and AutomationProperties in resource.resw for the tabitem it worked. I'll close the bug.
