There is some behavior change regarding the new WrapWithSafeLetCall quickfix
1. it now works correctly on binary expressions by wrapping it with `()`
2. it now looks for a nullable position upward and do the modification there,
if possible. For example, consider the following code
```
fun bar(s: String): String = s
fun test(s: String?) {
bar(bar(bar(<caret>s)))
}
```
After applying this fix, FE1.0 yields
```
bar(bar(s?.let { bar(it) }))
```
while the new implementation yields
```
s?.let { bar(bar(bar(it))) }
```
This behavior aligns with FE1.0 if `bar` accepts nullable values.
Previsously, errors have been ignored because we ignored errors raised
from the completion phase

The change in FirDeclarationUtil is needed because in case of unsigned
types loaded from the standard library, the primary constructor for some
reason is not the first, but the second in the list of constructors.
This will be used at least in the JVM backend instead of the current
approach where we're loading the primary constructor's first parameter,
which isn't good enough since primary constructor can be private, and
we can't rely on private declarations in case they're declared in
another module.
This commit adds the following actions:
- quickfix to implement missing members
- quickfix to implement missing members as constructor parameters
- action to implement members (Code - Generate - Implement)
- action to override members (Code - Generate - Override)
The current implementation is still missing some pieces, which will be
addressed in future changes.
- fully qualified names are not shorten
- some Kotlin types are not rendered correctly
This is needed to reuse EffectiveVisibility in FIR, because typeContext
in it is used to call `isSubtypeOf`, and in FIR it's required to use
context from use site session (to see all declaration which are
available in module)
KotlinTypeMapper.mapInlineClassTypeAsDeclaration and
mapUnderlyingTypeOfInlineClassType invoked mapType which is defined in
descriptorBasedTypeSignatureMapping.kt and works on KotlinType.
It didn't lead to any problems, other than the fact that we were
constructing IrBasedClassDescriptor in JVM IR, and then KotlinType to
pass it to mapType, on each call to StackValue.boxInlineClass or
unboxInlineClass, which seems wasteful.
Instead of this, refactor these utilities to use type markers instead,
pass IrType and IrTypeMapper directly from JVM IR, and move the "static
type mapper" logic (which is used only in the old backend) out of
KotlinTypeMapper.
Use {de,}capitalizeAsciiOnly and to{Lower,Upper}CaseAsciiOnly where
possible, and stdlib's functions with Locale.US everywhere else.
Otherwise, if the default system locale is Turkish, the capital latin
letter "I" is transformed in toLowerCase to "ı" (see
https://github.com/JetBrains/kotlin/blob/66bc142f92085047a1ca64f9a291f0496e33dd98/libraries/stdlib/jvm/test/text/StringJVMTest.kt#L119),
which for example breaks the codegen for `intArrayOf` in
KT-25400/KT-43405.
Similarly, lower case latin letter "i" is transformed to "İ".
