Cache the AOT compiler path, to avoid an expensive recomputation on every
build. This is even more expensive when building remotely from Windows, so
store the cached value on Windows.

Fixes #16774.

The only thing I would suggest, is $(_AOTCompiler) might collide with someone else trying to use the same name? Something in the .NET SDK or Mono workload.

In Android, I would name it $(_AndroidAOTCompiler) to avoid that, so I don't know if you normally use Apple as a prefix or something else.

Use a more unique property name than _AOTCompiler (use _XamarinAOTCompiler
instead) to try to prevent any problems if somebody else tries to use
'_AOTCompiler' somewhere.
