Integrate the `devices` respository (#30974)

Despite the name of this dependency, it only handles bluetooth. Because
it's a separate repository. Integrating it, allows changes here to be
tested more consistently. In addition, it's likely that new bluetooth
libraries will allow removing the majority of the platform-specific code
in this directory.

This is based on the version of this dependency from:
https://github.com/servo/devices/pull/34

+# Bluetooth Rust lib using macOS CoreBluetooth
+
+[![Build Status](https://travis-ci.org/akosthekiss/blurmac.svg?branch=master)](https://travis-ci.org/akosthekiss/blurmac)
+[![Crates.io](https://img.shields.io/crates/v/blurmac.svg)](https://crates.io/crates/blurmac)
+
+The main aim of BlurMac is to enable [WebBluetooth](https://webbluetoothcg.github.io)
+in [Servo](https://github.com/servo/servo) on macOS. Thus, API and implementation
+decisions are affected by the encapsulating [Devices](https://github.com/servo/devices),
+and the sibling [BlurZ](https://github.com/szeged/blurz) and [BlurDroid](https://github.com/szeged/blurdroid)
+crates.
+
+
+## Run Servo with WebBluetooth Enabled
+
+Usually, you don't want to work with BlurMac on its own but use it within Servo.
+So, most probably you'll want to run Servo with WebBluetooth enabled:
+
+```
+RUST_LOG=blurmac \
+./mach run \
+    --dev \
+    --pref=dom.bluetooth.enabled \
+    --pref=dom.permissions.testing.allowed_in_nonsecure_contexts \
+    URL
+```
+
+Notes:
+* The above command is actually not really BlurMac-specific (except for the `RUST_LOG`
+  part). It runs Servo with WBT enabled on any platform where WBT is supported.
+* You don't need the `RUST_LOG=blurmac` part if you don't want to see BlurMac debug
+  messages on the console.
+* You don't need the `--dev` part if you want to run a release build.
+* You don't need the `--pref=dom.permissions.testing.allowed_in_nonsecure_contexts`
+  part if your `URL` is https (but you do need it if you test a local file).
+
+
+## Known Issues
+
+* Device RSSI can not be retrieved yet.
+* Support for included services is incomplete.
+* Descriptors are not supported yet.
+* Notifications on characteristics are not supported yet (the limitation comes from
+  Devices).
+
+
+## Compatibility
+
+Tested on:
+
+* macOS Sierra 10.12.
+

+# Bluetooth Rust lib using macOS CoreBluetooth
+
+[![Build Status](https://travis-ci.org/akosthekiss/blurmac.svg?branch=master)](https://travis-ci.org/akosthekiss/blurmac)
+[![Crates.io](https://img.shields.io/crates/v/blurmac.svg)](https://crates.io/crates/blurmac)
+
+The main aim of BlurMac is to enable [WebBluetooth](https://webbluetoothcg.github.io)
+in [Servo](https://github.com/servo/servo) on macOS. Thus, API and implementation
+decisions are affected by the encapsulating [Devices](https://github.com/servo/devices),
+and the sibling [BlurZ](https://github.com/szeged/blurz) and [BlurDroid](https://github.com/szeged/blurdroid)
+crates.
+
+
+## Run Servo with WebBluetooth Enabled
+
+Usually, you don't want to work with BlurMac on its own but use it within Servo.
+So, most probably you'll want to run Servo with WebBluetooth enabled:
+
+```
+RUST_LOG=blurmac \
+./mach run \
+    --dev \
+    --pref=dom.bluetooth.enabled \
+    --pref=dom.permissions.testing.allowed_in_nonsecure_contexts \
+    URL
+```
+
+Notes:
+* The above command is actually not really BlurMac-specific (except for the `RUST_LOG`
+  part). It runs Servo with WBT enabled on any platform where WBT is supported.
+* You don't need the `RUST_LOG=blurmac` part if you don't want to see BlurMac debug
+  messages on the console.
+* You don't need the `--dev` part if you want to run a release build.
+* You don't need the `--pref=dom.permissions.testing.allowed_in_nonsecure_contexts`
+  part if your `URL` is https (but you do need it if you test a local file).
+
+
+## Known Issues
+
+* Device RSSI can not be retrieved yet.
+* Support for included services is incomplete.
+* Descriptors are not supported yet.
+* Notifications on characteristics are not supported yet (the limitation comes from
+  Devices).
+
+
+## Compatibility
+
+Tested on:
+
+* macOS Sierra 10.12.
+
+
+## Copyright and Licensing
+
+Licensed under the BSD 3-Clause [License](LICENSE.md).
