Add a new method `isImplicitReferenceToCompanion` to determine
if the given reference is an implicit reference to a companion object.
The method is needed for the rename refactoring in IJ.

Otherwise, e.g., if a local type is within an anonymous object, full
class id will include that anonymous object too, resulting in invalid
type signature for PsiType.

In case of broken code e.g., duplicated classes provider would return first class,
though we definitely need some code insight in this case
at least to add navigation fixes, etc.
Similar to this, a file copy is created during completion,
where additional elements might appear and we need to search for them.
Added test cases for duplicated classes.
CompileTimeConstantProvider could receive a reference expression,
whose grandparent is KtTypeReference (seen that in UAST inspection).
FIR would not contain anything explicit for this reference,
FirResolvedTypeRef would be received as the nearest parent.
Of course, in this case, there could be no compile time constant anyway.
then, for compiled code deserialized fir would be used instead of building
decompiled text and consequence building and resolving of raw fir;
type for ktTypeReference from compiled code is called e.g., by UAST inspections
when they check annotations of the called function parameters
Previously, the semantic was more-or-less correct for most of the cases
but some corner one, like `sort` in MutableList didn't work properly.
Namely, `sort` should be marked there in a way to forbid to call it
everywhere beside super-calls.
Also, overriding it should be allowed.
Mostly, the logic was re-written to K2 model from K1-related
JvmBuiltInsCustomizer.

this gives the following benefits:
1. no protobuf in memory, all data is already present in stubs
2. given that symbol provider for libraries is already stub based,
we can get rid of complicated code to find source psi by deserialized fir
3. it's also possible to reduce number of index access,
when fir is requested for given ktElement
If property call receiver is something real (like another property or a
function call), then it should not be shortened because the semantics
might change

The existing K2 reference shortener collects all the PSI elements to
shorten. As a result, it possibly shortens duplicated PSI elements. For
example,
```
// FILE: main.kt
package a.b.c
fun test(n: Int) {
return if (<expr>x.y.z.Outer.Inner.VALUE0 > x.y.z.Outer.Inner.VALUE1</expr>) 1
else n
}
// FILE: values.kt
package x.y.z
class Outer {
object Inner {
val VALUE0 = 13
val VALUE1 = 17
}
}
```
for the above code, the existing K2 reference shortener tried to shorten
- x.y.z.Outer.Inner -> Inner
- x.y.z.Outer.Inner.VALUE0 -> VALUE0
- x.y.z.Outer.Inner -> Inner
- x.y.z.Outer.Inner.VALUE1 -> VALUE1
`x.y.z.Outer.Inner` is included in the list to shorten twice.
When it actually shortens the PSI elements, it shortens only
- x.y.z.Outer.Inner.VALUE0 -> VALUE0
- x.y.z.Outer.Inner.VALUE1 -> VALUE1
but it imports all of
- x.y.z.Outer.Inner
- x.y.z.Outer.Inner.VALUE0
- x.y.z.Outer.Inner.VALUE1
As a result, it has unnecessary additional import directives.
This commit fixes the issue by avoiding duplicated shortening for a
single PSI element.
Those scopes always contain all nested classifiers,
while only some of them are available without
explicit import. There are other, more reliable
scopes (like FirNestedClassifierScopeWithSubstitution)
which are stricter about which classifiers
they recognise as valid

If an annotation doesn't specify an explicit use-site target,
previously it was added to both, the primary constructor value parameter
and the property in the FIR. Then, in FIR2IR, only the "correct" one was
added to the IR. Move up the deduplication logic into the frontend.
^KT-56177 Fixed
Support FirStringConcatenationCall in FirCompileTimeConstantEvaluator.
This allows string templates ("foo${bar}") to be evaluated as constants,
assuming the interpolated expressions are themselves constant.
In addition, fixes some handling bugs with KtConstantEvaluationMode,
where some expressions that are not valid in a `const val` declaration
were being supported for `CONSTANT_EXPRESSION_EVALUATION`, including
non-static final Java fields in FIR, and composite expressions of
non-const properties in FE1.0.
Use expanded ConeTypes to get correct parameters and return types
Also, fix the order of rendering modifiers in `KtFunctionalTypeRenderer`
