This patch allows expressions to reference entities in anonymous
namespaces. Previously this would have resulted in:
```
(lldb) expr foo::FooAnonymousVar
error: <user expression 0>:1:6: no member named 'FooAnonymousVar' in namespace 'foo'
1 | foo::FooAnonymousVar
| ~~~~~^
```
We already allow such lookups through inline namespaces, and for the
purposes of lookup, anonymous namespaces shouldn't behave any different.
Fixes https://github.com/llvm/llvm-project/issues/96963.
**Summary**
In a program such as:
```
namespace A {
namespace B {
struct Bar {};
}
}
namespace B {
struct Foo {};
}
```
...LLDB would run into issues such as:
```
(lldb) expr ::B::Foo f
error: expression failed to parse:
error: <user expression 0>:1:6: no type named 'Foo' in namespace 'A::B'
::B::Foo f
~~~~~^
```
This is because the `SymbolFileDWARF::FindNamespace` implementation
will return *any* namespace it finds if the `parent_decl_ctx` provided
is empty. In `FindExternalVisibleDecls` we use this API to find the
namespace that symbol `B` refers to. If `A::B` happened to be the one
that `SymbolFileDWARF::FindNamespace` looked at first, we would try
to find `struct Foo` in `A::B`. Hence the error.
This patch proposes a new `SymbolFileDWARF::FindNamespace` API that
will only find a match for top-level namespaces, which is what
`FindExternalVisibleDecls` is attempting anyway; it just never
accounted for multiple namespaces of the same name.
**Testing**
* Added API test-case

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:

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.
