Describe the bug:
Servo.app (aarch64) on macOS reported in system profiler as "iOS" app (resp. "arch_ios") rather than "Apple Chips" (resp. "arch_arm") app on an Apple Silicon System.

To Reproduce:

1. Open System Profiler app ('/System/Applications/Utilities/System Information.app')
2. Go to Section "Software" -> "Applications"
3. Select row of Servo app in column "Application Name" and have a look look at column "Kind"

Alternatively, via Shell/Terminal.app:
% system_profiler SPApplicationsDataType -xml | grep Servo -A 3 -B 2
or resp.
% system_profiler SPApplicationsDataType -xml | grep Servo -A 3 -B 2 | head -n 5 | grep -A 1 arch_kind

Expected Behavior:
Servo app is shown as "Apple Chips" resp. "arch_arm"
Actual Behavior:
Servo app is shown as "iOS" resp. "arch_ios"

Proposed simple fix/solution:

Add a CFBundleSupportedPlatforms key with MacOSX as its only platform to the app's Info.plist file:

<key>CFBundleSupportedPlatforms</key>
<array>
    <string>MacOSX</string>
</array>

The behavior does only occur on macOS aarch64 binaries, not on Intel or Universal build binaries. See also issuecomment-820653677 on microsoft/vscode#121169 (comment):

Its just an issue with which attribute the storage info queries to decide the kind, the output of system_profiler SPApplicationsDataType -xml shows the arch_kind is arch_ios. I think these look for CFBundleSupportedPlatforms attribute and if not present default to the ios kind for arm64 executables.

Given the universal and intel labels show up correctly, and considering the output of other apple silicon apps in the image posted.

BTW: Apple's own macOS apps and most third party apps contain that key in their Info.plist, so, it can't be wrong or invalid and is there for a reason, although not or poorly documented by Apple.
