This adds a new status file indicator "HEAVY" to mark tests with high
resource demands. There will be other tests running in parallel,
but only a limited number of other heavy tests. The limit is
controlled with a new parameter --max-heavy-tests and defaults to 1.

The change also marks a variety of tests as heavy that recently had
flaky timeouts. Heavy also implies slow, hence heavy tests are
executed at the beginning with a higher timeout like other slow tests.

The implementation is encapsulated in the test-processor chain. A
new processor buffers heavy tests in a queue and adds buffered tests
only if other heavy tests have ended their computation.

LookupResult instead of references to the individual arguments.

We used to recompile WasmCapiCallWrappers whenever they were
needed, but never garbage-collected them, which caused a memory
leak when many short-lived instances of the same module were
created. This patch makes the wrappers cacheable and caches them,
which avoids both repeated compilation effort and the unbounded
memory growth.
Drive-by cleanup: unify WasmCapiFunctionData with the other
Wasm*FunctionData classes by making it inherit from WasmFunctionData.

When adding new instances to the WeakArrayList of a script's
instances, use Append() instead of AddToEnd() to allow possible
compaction of the WAL.
Also, check for interrupt requests every now and then, which
allows incremental marking to get finalized when appropriate.
