gh-144418: Increase Android testbed emulator RAM to 4 GB

[mhsmith]

• Fixes Android testbed emulator needs more RAM #144418

!buildbot android

!buildbot aarch64 Android

Testing this has completely broken the aarch64 buildbot in a similar way to #142387, so I've taken it offline until I have a chance to fix it.

[mhsmith]

Specifically, I deleted the existing emulator, and it failed to recreate because it got stuck in a loop of "EGLContext creation failed" crashes. However, the problem isn't specific to this PR; it also happens on the main branch now that the old emulator is gone.

I'll fix this next week, but I don't think it needs to hold up this PR. It works on GitHub Actions, which was its main purpose, and on the x86_64 buildbot. And I've tested it locally on an aarch64 macOS machine, including all of the following cases:

• Emulator doesn't exist
• Emulator exists and its RAM size needs to change
• Emulator exists and its RAM size doesn't need to change

The RAM size can be displayed using the following command:

./android.py test --managed maxVersion -v -- -c 'print([line for line in open("/proc/meminfo") if "MemTotal" in line][0])'

Annoying that it's needed, but this all makes sense, and works well in my testing.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false
