Those modules are:
- :compiler:fir:providers, which contains Fir and Symbol providers,
scopes, and different utilities used by them
- :compiler:fir:semantics, which contains different abstractions and
entities which are used in resolution and in checkers
- :compiler:fir:resolve, which contains all stuff related to resolution
and inference
There are two pros of this change:
1. It may increase gradle build, because it allows to compile :fir:resolve
and :fir:checkers modules in parallel
2. Logic of working FIR (scopes, providers, DFA logic system, etc) is
now separated from logic of resolution phases, so for example checkers,
which are depend on scopes physically will not be able to run resolve
in any way
Instead of a Boolean flag -Xserialize-ir, use modes: none,inline,all.
In "inline" mode, only information needed to deserialize bodies of inline
functions is serialized.
In the "all" mode, all declarations are serialized completely.
The only way to make the compiler compile several modules with a
dependency loop is via the "build file", given by -Xbuild-file and used
in the JPS (IntelliJ built-in build system) plugin.
For the old frontend/backend it works like this: we _analyze_ sources of
all modules once, as if it's one big module, and then for each module,
we _generate_ (invoke backend) only sources of that module. Backend
needs to be invoked separately per-module because every module has its
own destination directory specified in the build file.
For JVM IR, this separation into just two steps, analyze and generate,
was problematic because there's psi2ir, which works like frontend, in
that it needs the global analysis result to be able to create and link
IR correctly. So, in case of JVM IR, we need to run psi2ir on the whole
module after analysis and before generation.
In this change, psi2ir is run on the whole module via
`CodegenFactory.convertToIr` (which does nothing in the old backend),
and then parts of the resulting IR module are extracted according to the
original separation of the combined module into individual modules via
`getModuleChunkBackendInput` by matching IrFile against KtFile. And
then, backend is run for each such module.

* Use fetch and instantiateStreaming
* Call main export if it is present
* Produce a variable with module name that contains a
promise of module exports
Together with extracting codegen to a separate (unrelated) module in the
future, hopefully it'll speed up the build of JVM IR by making it more
parallel, and helping incremental compilation to avoid recompiling code
that depends on lowerings because of `implementation` dependency.
- change test runner to production mode when sources are being compiled
into klib and then klib is being translated into js, not directly from
kt to js
- fix IC cache format
- support IC tests
