Introduce Bluetooth Support for Magic Trackpad 2

Introduce initial Bluetooth connectivity support for Magic Trackpad 2. Work is still in-progress so you might experience certain issues such as input lag or system crash. I've selfhosted it for several days and ironed a bunch of bugs out, but the issue list might not be exhaustive. Feel free to open a bug and provide crash dump securely so I can figure out what else needs to be resolved.

Battery status indicator and plug-and-pair (from USB to Bluetooth) are still work-in-progress, please wait patiently and I believe these will come to you soon.

Bluetooth: How to use

• Install the driver as usual.
• Then just go to Bluetooth settings and pair your trackpad.

Known Caveats

• On certain systems such as Surface Pro X, first time Bluetooth connectivity might take a long time to finish (5-10 seconds.) Please wait patiently. A toast prompting "restart system" might show up, which is a false-positive message, and you can safely ignore that.
• It doesn't work well with VMware workstation Bluetooth controller passthrough, and I don't think there's much I can do with VMware.

AzDO build record

https://ligstd.visualstudio.com/Apple%20PTP%20Trackpad/_build/results?buildId=3979

This update bumps version scheme and fully meets DCH driver isolation requirements.

This update addressed two issues:

• Addressed the input lag issue for USB implementation.
• Addressed the S3 wakeup malfunction/failure for SPI implementation.

• More support for MacBook Air 2020 (#321)

• Added support for 2020 MacBook family (#308, #295.)

• Addressed dead zone touch problems with MacBook Pro 15/16inch models with T2 coprocessor (#242).

Drivers are now Microsoft attestation signed! So you can install it without disabling Secure Boot.

• Added support for a few 16-inch MacBook Pro and MacBook Air 2011/2012. The 16-inch support comes with a known deadzone.
• Starting from this version, only user distribution packages are attached in release. To retrieve debug symbols, check AzDevOps artifacts.

• All drivers are merged into a single distribution package to improve the installation experience.
• Partially mitigated the SPI trackpad S3 resume with some possible side-effects.

Note: drivers are re-released to eliminate the confusion of multiple build paths. To retrieve build symbols for debugging, check AzDevOps artifacts.

• Added a generic fallback for all known Apple T2-based devices. Experience might not be optimal for a few devices due to the lack of calibration data, please open a issue if you encountered problems such as dead touch regions.

• Mitigated (not yet fully addressed) random touch rejection for Magic Trackpad 2: should address issues in #212, #170, #166, #163, #161, #94, #38, #37 and #83. I would like to thank @rikumi and @CFSO6459 for reporting as well as endorsing my project. :)
• Addressed an issue which a subset of T2 devices was unexpectedly declared in the um driver.

• Addressed significant memory leaks for SPI trackpads
• Improved synchronization mechanism for SPI trackpads

• Addresses an issue which causes a few T2 trackpads do not have HID descriptor reported

• Added 7a and 7b T2 trackpad model in the INF file

• Support for a few more T2-based models such as MacBook Air.

• Addresses IRQL & page fault bugcheck on T2 devices.

• Validates device buffer in the interrupt routine for T2 devices. This might fixed #202 but needs further testing.

• Addresses certificate issues on SPI/T2 devices.

• Fixed T2 sleep bugcheck.

Hello from Disneyland California :)

• Experimental T2 support
• Prod-signed SPI driver so no TestSigning needed

Fixed

• Touchpad report timing, which improved acceleration in some scenarios.

Notes

• SPI and MacBook Pro (15-inch, 2015) is not supported by this release. Code is not merged yet.

What's new in this release

• Wellspring type 5A support. Models like MacBook Pro (Late 2011) and MacBook Pro (Mid 2012) are supported now. See #62 for more details.

What if I encounter a driver issue?

Submit a driver trace file like #62 (replace symbol file though). I will explain more in a coming issue template.
