Enable the src/controller tests on all platforms except nrfconnect.

[bzbarsky-apple]

1. Modify our CHIPClientCallbacks template to suppress the "possibly
   unbounded stack" warning from a VLA we know we want to remove.
2. Don't try to link in BLELayer in the TestDevice test if BLE
   networking is disabled (so that BLELayer symbols don't actually
   exist).
3. Heap-allocate the huge FabricTable so we don't run into compile
   errors due to a stack frame being too big in TestDevice.
4. Fix the fact that SystemLayerImplSelect did not default-initialize
   mDispatchQueue. This matters because TestDevice does weird things
   with a separate SystemLayer that the PlatformManager does not know
   about, nor does it call InitChipStack in any case.

The tests are still disabled on nrfconnect because I could not get
them to link there so far.

Fixes #9173

Problem

Tests were disabled on Darwin, probably because the actual test BUILD.gn did not spell "darwin" right, so did not end up linking in the right things, so linking failed.

Change overview

Always link in the right things, plus the items above.

Testing

CI passes.
