Add timeout to prevent infinite wait in TestMIDDriver test

[coderabbitai]

Problem

The getTempo test in TestMIDDriver.cpp contains a busy-wait loop that could potentially hang indefinitely on flaky platforms:

while (!md.isTempoChanged()) {
    utils::delayMillis(10);
}

This can cause CI builds to hang under certain conditions, especially when running with -Werror flags.

Context

• File: sdl2-hyper-sonic-drivers/test/HyperSonicDrivers/drivers/TestMIDDriver.cpp
• Lines: 112-116
• Original PR: Build GCC MSYS2 UCRT64 #290
• Discussion: Build GCC MSYS2 UCRT64 #290 (comment)

Expected Solution

Add a timeout mechanism (e.g., 2 seconds) to the wait loop with proper test failure handling to ensure tests complete reliably.
