Page allocation in a partially-reserved sandbox is generally best-effort
once the reserved part is fully allocated, which happens in this test.
As such, there is no guarantee that this test succeeds, and it does seem
to fail in practice on some bots with memory sanitizers enabled. The
same logic is essentially tested by the
VirtualAddressSpaceTest.TestEmulatedSubspace test so simply deleting
this test should be fine.

Original Commit Message:
So far, discarded size was maintained by the sweeper but not wired up
anywere.
Changes in this patch:
- Wire up resident size in heap statistics collection.
- Fix bugs in reporting committed and resident size.
- Sweeper test: Enforce some internal details. The details should not
not be checked broadly but be kept as a detail to the sweeper
itself.
- Stats collection: Test that committed and resident set size are
reported and differ after discarding GCs.

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.

This CL introduces a test runner flag to detect if webassembly has been
disabled. Since all tests that require wasm are alrady skipped in
lite mode, we introduce a has_webassembly flag for the test runner which
checks for v8_enable_webassembly=true and v8_enable_lite_mode=false.
As a drive-by, we also do not set the V8_ENABLE_WEBASSEMBLY
preprocessor flag if lite mode is enabled.
The status files are updated by splitting wasm tests from the
"lite_mode" section and checking for "not has_webassembly" instead.
Note that the v8_enable_webassembly=false configuration is not tested
on any bot currently, but I will make sure that all tests keep passing
on further changes in this configuration.

Apple's upcoming arm64 devices will prevent rwx access to memory,
but in turn provide a new per-thread way to switch between write
and execute permissions. This patch puts that system to use for
the WebAssembly subsystem.
The approach relies on CodeSpaceWriteScope objects for now. That
isn't optimal for background threads (which could stay in "write"
mode permanently instead of toggling), but its simplicity makes
it a good first step.
