This changes Python API tests to use a single build shared across all
test functions, instead of the previous default behavior of a separate
build dir for each test function.
This build behavior opt-out, tests can use the previous behavior of one
individual (unshared) build directory per test function, by setting
`SHARED_BUILD_TESTCASE` to False (in the test class).
The motivation is to make the test suite more efficient, by not
repeatedly building the same test source. When running tests on my macOS
machine, this reduces the time of `ninja check-lldb-api` by almost 60%
(sample numbers: from ~492s down to ~207s = 58%). Almost 5min time
saved.
Each test function still calls `self.build()`, but only the first call
will do a build, in the subsequent tests `make` will be a no-op because
the sources won't have changed.
This patch is a reworking of Pete Lawrence's (@PortalPete) proposal
for better expression evaluator error messages:
https://github.com/llvm/llvm-project/pull/80938
Before:
```
$ lldb -o "expr a+b"
(lldb) expr a+b
error: <user expression 0>:1:1: use of undeclared identifier 'a'
a+b
^
error: <user expression 0>:1:3: use of undeclared identifier 'b'
a+b
^
```
After:
```
(lldb) expr a+b
^ ^
│ ╰─ error: use of undeclared identifier 'b'
╰─ error: use of undeclared identifier 'a'
```
This eliminates the confusing `<user expression 0>:1:3` source
location and avoids echoing the expression to the console again, which
results in a cleaner presentation that makes it easier to grasp what's
going on. You can't see it here, bug the word "error" is now also in
color, if so desired.
Depends on https://github.com/llvm/llvm-project/pull/106442.

This is an ongoing series of commits that are reformatting our Python
code. Reformatting is done with `black` (23.1.0).
If you end up having problems merging this commit because you have made
changes to a python file, the best way to handle that is to run `git
checkout --ours <yourfile>` and then reformat it with black.

Eliminate boilerplate of having each test manually assign to `mydir` by calling
`compute_mydir` in lldbtest.py.

Fix to get the AST we generate for function templates closer to what clang generates and expects.
We fix which FuntionDecl we are passing to CreateFunctionTemplateSpecializationInfo and we strip
template parameters from the name when creating the FunctionDecl and FunctionTemplateDecl.
These two fixes together fix asserts and ambiguous lookup issues for several cases which are added to the already existing small function template test.
This fixes issues with overloads, overloads and ADL, variadic function templates and templated operator overloads.

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

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.
