Fixes github issues #59178, #58464 and #62799.
The problem was that the LevelIndentTracker remembered
the indentation level of previous deeper levels when
leaving a scope. Afterwards, when it entered again a
deeper level, it blindly reused the previous
indentation level. In case the --lines option was used
such that the previous deeper level was not formatted,
that previous level was whatever happened to be there
in the source code. The formatter simply believed it.
This is fixed by letting the LevelIndentTracker forget
the previous deeper levels when stepping out of them
(=> change in LevelIndentTracker::nextLine()).
Note that this used to be the case until LLVM 14.0.6,
but was changed in https://reviews.llvm.org/D129064
(#56352) to fix a crash. Our commit here essentially
reverts that crash fix. It was incorrect/incomplete.
Even with the revert, the crash from
https://reviews.llvm.org/D129064 (#56352) no longer
occurs, most likely because of the changes made in
https://reviews.llvm.org/D144296 (#60843).
The change in adjustToUnmodifiedLine() ensures that
the assert() is only checked if IndentForLevel is
actually accessed.
The new test FormatTestSelective.DontAssert checks
a case where a previous iteration of the present
patch triggered an assert().
The new tests in
FormatMacroRegardlessOfPreviousIndent check the
formatting of a preprocessor #define. They ensure
that the content of LevelIndentTracker::IndentForLevel
does not affect PP directives.

NOTE: Clang-Format Team Automated Review Comment
It looks like your clang-format review does not contain any unit tests, please
try to ensure all code changes have a unit test (unless this is an `NFC` or
refactoring, adding documentation etc..)
Add your unit tests in `clang/unittests/Format` and you can build with `ninja
FormatTests`. We recommend using the `verifyFormat(xxx)` format of unit tests
rather than `EXPECT_EQ` as this will ensure you change is tolerant to random
whitespace changes (see FormatTest.cpp as an example)
For situations where your change is altering the TokenAnnotator.cpp which can
happen if you are trying to improve the annotation phase to ensure we are
correctly identifying the type of a token, please add a token annotator test in
`TokenAnnotatorTest.cpp`
