What is happening?

Prerequisites

• Run all flutter/flutter macOS tests manually on macOS 14.5 bot #148868
• Update .ci.yaml in flutter/flutter to use either macOS 13 or macOS 14 #148871
• Ensure no open issues in ☂️ Tracking issue for any infra or test failures with macOS 14 #148882

Upgrade ~50% of bots to macOS 14.5 per arch per pool

• Always leave at least 2 bots per arch in the try and prod pools on macOS 13 to maintain beta/stable - 1 to run tests and 1 as a backup
• beta/stable doesn't use staging so don't need to reserve bots in staging pool

Device lists:

• Try pool - iOS arm64 bots
• Try pool - iOS x86 bots
• Try pool - Android bots
• Staging pool - iOS arm64 bots
• Staging pool - iOS x86 bots
• Staging pool - Android arm64 bots
• Staging pool - Android x86 bots
• Prod pool - iOS arm64 bots
• Prod pool - iOS x86 bots
• Prod pool - Android arm64 bots
• Prod pool - Android x86 bots

When ready to upgrade, file an issue with a list of explicit bots listed by name to upgrade and additional instructions. See #148859 as example

If something goes wrong or tests begin to fail, .ci.yaml changes from #148871, #148873, #148879 can be reverted if necessary.
