Promise.{all,allSettled,any,race} should check resolve is a function before

PR: https://github.com/tc39/ecma262/pull/1912
PR for Promise.any: https://github.com/tc39/proposal-promise-any/pull/65
This CL includes the following cleanup changes:
- Made it more explicit that the constructor is a Constructor.
- Removed unnecessary nested try blocks (a try can have both a catch and a label).
- Moved commonly used definitions out of promise-race.tq where they don't belong.
- Made the parameter order of PerformPromiseAll match the spec.

The {NONE} reloc info is the one used most often, i.e. for every
assembler call that takes an {Immediate} on x64 which is not
relocatable.
Hence assign value 0 to {NONE} such that constructing such immediates is
faster and also checking for this most common case is faster.

Avoid going through the {WasmDebugInfo}, which existed for debugging in
the interpreter in production. Instead, tests now instantiate the
interpreter directly.
This will unblock the removal of the whole {WasmDebugInfo}, and finally
moving the interpreter to the test directory.

The reference stack was set by the scope, and reset when leaving the
scope, in order to avoid leaking objects via cycles in the reference
tree, involving global handles which are considered strong roots.
Since the interpreter cannot call out to JS any more, we cannot create
such cycles any more. Hence, the ReferenceStackScope is removed, and the
FixedArray for the reference stack is allocated as a global handle
instead.
This will unblock removing the WasmDebugInfo object, which was used by
the ReferenceStackScope before this CL.

A previous CL removed the kNoThrow flags from both
SpeculativeBigIntAdd and SpeculativeBigIntSubtract. This introduced a
bug, because the JSTypeHintLowering phase, where these operators are
introduced during inlining, does not support the generation of throwing
operators.
Since these operators always deoptimize in case of an error, instead of
throwing the exception directly, it is safe to mark them as kNoThrow.

Adds allocation-based heap growing strategy that triggers GC based on
some limit. The limit is computed based on previous live memory and a
constant growing factor.
For invoking GC, we support two modes: with and without conservative
stack scanning. Without conservative stack scanning, an invoker makes
sure that we schedule a GC without stack using the existing platform.

When the last debugger is disabled, we tier up the module to TurboFan.
Doing this in the background creates problems with profiling, where the
debugger is disabled before starting to profile, in order to guarantee
profiling of top-tier code.
Hence this CL changes the logic such that we only return from the
{TierUpAllModulesPerIsolate} methods once tier up is complete. Since
the DevTools frontend disables all debuggers before starting a profile,
this will ensure that all new calls execute TurboFan code.
Because of this change, the {TriggerRecompilation} method is renamed to
{RecompileForTiering}.
The test cases stay unchanged (do a busy wait until tier up is done),
because in the multi-isolates tests it is not guaranteed that tier up is
complete after disabling a single debugger.

> Since ReadOnlySpace no longer uses most of the code from the other
