Fix generic spi graphics setup

[mikmog]

Description

Fixes two issues in Generic_SPI graphic driver.

• OS_DELAY cmd enum unintended use. Calculates wait in milliseconds. Cmd enum has value of 1.
• SetupDisplayAttributes, Setting height for wrong side.

Motivation and Context

Discovered during development. Breakout to own PR.
General improvements and bug fixes.

How Has This Been Tested?

On an ESP32_S3 Feather and Ili9488 display

📝 Summary

Summary by CodeRabbit

Bug Fixes

• Corrected display dimension handling for configured screen heights.
• Fixed display sleep timing calculations.

Walkthrough

This change fixes two SPI display driver issues. Sleep delays now use the command size directly. Configured display height now updates Attributes.ShorterSide.

Changes

SPI Display Driver Corrections

Layer / File(s)	Summary
Sleep delay calculation src/nanoFramework.Graphics/Graphics/Displays/Generic_SPI.cpp	ProcessCommand calculates sleep delays from *size without multiplying by the command byte.
Display attribute assignment src/nanoFramework.Graphics/Graphics/Displays/Generic_SPI.cpp	The height fallback branch assigns configured height to Attributes.ShorterSide and removes the empty statement.

Estimated code review effort: 1 (Trivial) | ~3 minutes

Merge Risk: ⚪ Minimal · up to db042

This updates Generic SPI display sleep timing and height assignment to use the intended values. The current change corrects both behaviors with no identified merge-blocking risk.

Pull request overview

Fixes two correctness issues in the Generic_SPI display driver so that generic SPI-based display initialization behaves as intended (sleep delays actually delay, and configured dimensions map to the correct attribute side).

Changes:

• Fix sleep-delay handling in ProcessCommand() by removing unintended multiplication by the command enum value.
• Fix SetupDisplayAttributes() to apply configured Height to Attributes.ShorterSide (and remove a stray semicolon).
