LibJS: Remove "uprooting" mechanism from garbage collector

Browse source 
The Heap::uproot_cell() API was used to implement markAsGarbage() which
was used in 3 tests to forcibly destroy a value, even if it had
references on the stack or elsewhere.

This patch rewrites the 3 tests that used this mechanism to be
structured in a way that allows garbage collection to collect the values
as intended without hacks. And now that the uprooting mechanism is no
longer needed, it's uprooted as well.

This fixes 3 test-js tests in bytecode mode. :^)
