[2 pane layout] Tablet mode detection logic change

[AnirudhBhat]

Closes: #12861

Description

This PR refactors the tablet detection logic to account for both width and height dimensions when determining if a device qualifies as a tablet. The updated logic improves compatibility with larger phones especially in landscape mode.

Changes Introduced:
New Size Class Determination Method:

Introduced determineWindowSizeClassByDimensions(widthDp: Int, heightDp: Int).
Evaluates both shortSize and longSize (smallest and largest dimensions, respectively) to classify devices as Compact, Medium, or ExpandedAndBigger.

Steps to reproduce

1. Open WooCommerce app
2. Navigate to orders screen
3. Rotate your device
4. Observe the Behaviour:
   On smaller devices: The screen remains in single-pane mode and does not split into tablet mode.
   On larger phones and tablets: The screen transitions to split-pane (tablet) mode as expected.

The tests that have been performed

Verified behaviour on below emulators:
Tablets (portrait and landscape)
Large phones in landscape mode
