Add EGL_ANGLE_platform_angle_device_id for the Metal backend. This extension takes in a 64-bit device ID in two parts as parameters to eglGetPlatformDisplay and uses it to initialize a display backed by a specific device. The deviceID should match the MTLDevice's registryId.

EGL_ANGLE_display_power_preference interacts with this extension.

Overview
This extension enables the selection of a graphics device to back
an ANGLE EGLDisplay.
New Types
None
New Procedures and Functions
None
New Tokens
Accepted as an attribute name in the <attrib_list> argument of
eglGetPlatformDisplayEXT:
EGL_PLATFORM_ANGLE_DEVICE_ID_HIGH_ANGLE 0x34D6
EGL_PLATFORM_ANGLE_DEVICE_ID_LOW_ANGLE 0x34D7
Additions to the EGL Specification
None
New Behavior
To request a display that is backed by a specific graphics device,
EGL_PLATFORM_ANGLE_DEVICE_ID_HIGH_ANGLE and/or
EGL_PLATFORM_ANGLE_DEVICE_ID_LOW_ANGLE should be set to the high part and
low part of the device's ID. If only one attribute is specified, the other
is assumed to be zero. The device's ID is specific to the platform that
ANGLE is running on, but should fit into one 64-bit value.
If the high part and low part combined is zero, an EGL_BAD_ATTRIBUTE error
is generated and EGL_NO_DISPLAY is returned.
Add device id as a part of the key in EGLDisplay cache Otherwise eglGetPlatformDisplay would return displays created with other devices.

If the ID specified doesn't match any devices on the system, the device
is selected as described in the EGL_ANGLE_display_power_preference extension.
Add EGL_ANGLE_platform_angle_device_id for the Metal backend. This extension takes in a 64-bit device ID in two parts as parameters to eglGetPlatformDisplay and uses it to initialize a display backed by a specific device. The deviceID should match the MTLDevice's registryId.

- Describe interaction with EGL_ANGLE_display_power_preference,
EGL_ANGLE_platform_angle_device_id takes precedence.
Add EGL_ANGLE_platform_angle_device_id for the Metal backend. This extension takes in a 64-bit device ID in two parts as parameters to eglGetPlatformDisplay and uses it to initialize a display backed by a specific device. The deviceID should match the MTLDevice's registryId.
