[lldb][ClangASTImporter] Don't ASTImport LambdaExpr nodes (#154962)
This patch works around an assertion that we hit in the `LambdaExpr`
constructor when we call it from `ASTNodeImporter::VisitLambdaExpr` (see
https://github.com/llvm/llvm-project/issues/149477). The lambda that we
imported doesn't have the `NumCaptures` field accurately set to the one
on the source decl. This is because in `MinimalImport` mode, we skip
importing of lambda definitions:
e21b0dd819/clang/lib/AST/ASTImporter.cpp (L2499)

In practice we have seen this assertion occur in our `import-std-module`
test-suite when libc++ headers decide to use lambdas inside inline
function bodies (the latest failure being caused by
https://github.com/llvm/llvm-project/pull/144602).

To avoid running into this whenever libc++ decides to use lambdas in
headers, this patch skips `ASTImport` of lambdas alltogether. Ideally
this would bubble up to the user or log as an error, but we swallow the
`ASTImportError`s currently. The only way this codepath is hit is when
lambdas are used inside functions in defined in the expression
evaluator, or when importing AST nodes from Clang modules. Both of these
are very niche use-cases (for now), so a workaround seemed appropriate.

fdea9a4ec9 [lldb] Remove license headers from all test source files
Summary:
Around a third of our test sources have LLVM license headers. This patch removes those headers from all test
sources and also fixes any tests that depended on the length of the license header.

The reasons for this are:

* A few tests verify line numbers and will start failing if the number of lines in the LLVM license header changes. Once I landed my patch for valid SourceLocations in debug info we will probably have even more tests that verify line numbers.
* No other LLVM project is putting license headers in its test files to my knowledge.
* They make the test sources much more verbose than they have to be. Several tests have longer license headers than the actual test source.

For the record, the following tests had their line numbers changed to pass with the removal of the license header:
    lldb-api :: functionalities/breakpoint/breakpoint_by_line_and_column/TestBreakpointByLineAndColumn.py
    lldb-shell :: Reproducer/TestGDBRemoteRepro.test
    lldb-shell :: Reproducer/TestMultipleTargets.test
    lldb-shell :: Reproducer/TestReuseDirectory.test
    lldb-shell :: ExecControl/StopHook/stop-hook-threads.test
    lldb-shell :: ExecControl/StopHook/stop-hook.test
    lldb-api :: lang/objc/exceptions/TestObjCExceptions.py

99451b4453 [lldb][test] Remove symlink for API tests.
Summary: Moves lldbsuite tests to lldb/test/API.

This is a largely mechanical change, moved with the following steps:

```
rm lldb/test/API/testcases
mkdir -p lldb/test/API/{test_runner/test,tools/lldb-{server,vscode}}
mv lldb/packages/Python/lldbsuite/test/test_runner/test lldb/test/API/test_runner
for d in $(find lldb/packages/Python/lldbsuite/test/* -maxdepth 0 -type d | egrep -v "make|plugins|test_runner|tools"); do mv $d lldb/test/API; done
for d in $(find lldb/packages/Python/lldbsuite/test/tools/lldb-vscode -maxdepth 1 -mindepth 1 | grep -v ".py"); do mv $d lldb/test/API/tools/lldb-vscode; done
for d in $(find lldb/packages/Python/lldbsuite/test/tools/lldb-server -maxdepth 1 -mindepth 1 | egrep -v "gdbremote_testcase.py|lldbgdbserverutils.py|socket_packet_pump.py"); do mv $d lldb/test/API/tools/lldb-server; done
```

lldb/packages/Python/lldbsuite/__init__.py and lldb/test/API/lit.cfg.py were also updated with the new directory structure.
