Now KtFirScopeProvider do not contain caches, so it can be reused between the threads. The only thread-local thing it had, was a ScopeSession. Now it's not stored in the KtFirScopeProvider
Not fully initialized DeclarationDescriptor could leak to bindingTrace.
It is hard to detect the outcome of that kind of leakage due to
possibility to have not fully initialized instances if PCE happens in
the middle of publication and instance full initialization.

SimpleFunctionDescriptorImpl initialization consists of two phases:
ctor + initialize.
When SimpleFunctionDescriptorImpl is created wrapped descriptor
(e.g. ValueParameterDescriptorImpl) is leaked through bindingTrace
with not fully initialized `containingDeclaration` (that is
SimpleFunctionDescriptorImpl).
If PCE happens after this unsafe publication prior to `initialize` then
it will be case with NPE on fully initialized instance reading.

PropertyDescriptorImpl initialization consists of two phases:
ctor + setType.
When PropertyDescriptorImpl is created wrapped descriptor
(e.g. WithDestructuringDeclaration) is leaked through bindingTrace
with not fully initialized `containingDeclaration` (that is
PropertyDescriptorImpl).
If PCE happens after this unsafe publication prior to `setType` then it
will be case with NPE on fully initialized instance reading.

Because SerializationJvmIrIntrinsicSupport does not instantiate annotations yet,
this info could be lost. As a workaround, it is possible to call Companion.serializer()
functions instead of direct serializer instantiation, as they are plugin-generated
and correctly handle annotations.
Note that for some cases (enums & interfaces) this WA is not enough, so additional work
is needed later.

Apparently it depended on the ordering of the synthetic `$annotations`
methods generated for properties. And those methods were always
generated at the end of a Java stub by kapt because they lacked PSI
element, and thus `ClassFileToSourceStubConverter.convertClass` could
not compute their source position, and it placed them at the end as all
other synthetic methods.
The solution is to provide PSI element for `$annotations` methods in
JvmDeclarationOrigin. This origin is then collected in kapt in
`OriginCollectingClassBuilderFactory` and used for sorting, as in the
case of the old JVM backend.
