To do so, inside the root cause of inapplicable candidate errors,
we will record expected/actual type of receiver, if any.
That will help identifying inapplicable calls on nullable receiver.
Do not report same set of diagnostics for variable call if actual
error was happened with a function candidate. Here the candidate is
invoke function on DeepRecursiveFunction

^KT-40926 In Progress
Update includes:
- Changing syntax of `OI/`NI` tags from `<!NI;TAG!>` to `<!TAG{NI}!>`
- Fix some incorrect directives
- Change order of diagnostics in some places
- Remove ignored diagnostics from FIR test data (previously `DIAGNOSTICS` didn't work)
- Update FIR dumps in some places and add `FIR_IDENTICAL` if needed
- Replace all JAVAC_SKIP with SKIP_JAVAC directive
In particular, this commit includes:
* Attempt to abstract access to FirSourceElement via FirModifier
* Add more visit functions to DeclarationCheckersDiagnosticComponent
* Add messages+factories for 4 modifier-related errors and warnings
* Introduce FirModifierChecker
`isNullable` check returns `true` for flexible types,
which leads to false positive unsafe invoke error, when
receiver for invoke's property is flexible.

#KT-36247 fixed
A lot of testdata changed because significanly less (error) descriptors
are created for unresolved types, so diagnostics became different.
There are several issues with unsafe desugaring for convention calls.
Proper fix is not implemented here (see design proposal KT-30872).
This commit only applies the old logic in the new inference.
^KT-30695 Fixed
Coersion to Unit from error type leads to misleading type mismatches:
"expected <expected lambda return type> found Unit", despite no user-provided Unit / empty lambda.
These diagnostics were collected, but not reported before, and that had been disguising the issue for a while.
KT-34729 Fixed
Here we introduce ONLY_IMPLICIT_RECEIVER tower level
to support extension lambda calls on local variables,
and soften extension receiver checks to make such extensions visible & applicable.
Also here we try to map arguments twice for functional types
This commits introduces testdata changes, where NI behaviour strictly
improved, after several previous fixes.
For some tests, just WITH_NEW_INFERENCE directive was added. It
indicates, that some of previous commits first introduced error in that
test, and then some other commit fixed it (netting no overall testdata
change). It is preferrably to keep those annotations until we will
migrate to NI completely, to prevent unexpected regressions.
- locals win
- unary calls to plus/minus are not supported in favor of unaryPlus/unaryMinus
- unqualified nested classes are temporarily reported as unresolved
- function without receiver win against extension function
- explicit import win against star import
