If a server does not support allocating memory in an inferior process or
when debugging a core file, evaluating an expression in the context of a
value object results in an error:
```
error: <lldb wrapper prefix>:43:1: use of undeclared identifier '$__lldb_class'
43 | $__lldb_class::$__lldb_expr(void *$__lldb_arg)
| ^
```
Such expressions require a live address to be stored in the value
object. However, `EntityResultVariable::Dematerialize()` only sets
`ret->m_live_sp` if JIT is available, even if the address points to the
process memory and no custom allocations were made. Similarly,
`EntityPersistentVariable::Dematerialize()` tries to deallocate memory
based on the same check, resulting in an error if the memory was not
previously allocated in `EntityPersistentVariable::Materialize()`.
As an unintended bonus, the patch also fixes a FIXME case in
`TestCxxChar8_t.py`.

This is a fixup to https://github.com/llvm/llvm-project/pull/93808,
which used LDFLAGS instead of the correct LD_EXTRAS

When PIE is enabled on a platform by default, these tests fail since the
`target variable` command can't read a global string variable value
before running an inferior process.
It fixes the following tests when built with clang on Ubuntu aarch64:
```
commands/target/basic/TestTargetCommand.py
lang/c/global_variables/TestGlobalVariables.py
lang/cpp/char8_t/TestCxxChar8_t.py
```

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.

When targeting macOS Ventura, ld64 will use authenticated fixups for
x86_64 as well as arm64 (where that has always been the case). This
results in test failures when using an Xcode 14 toolchain on an Intel
mac running macOS Ventura:
Failed Tests (3):
lldb-api :: commands/target/basic/TestTargetCommand.py
lldb-api :: lang/c/global_variables/TestGlobalVariables.py
lldb-api :: lang/cpp/char8_t/TestCxxChar8_t.py
Rather than trying to come up with a sophisticated decorator based off
the deployment target, I marked them all as skipped with a comment
explaining why.

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

Split TestCxxChar8_t into two parts: one that check reading variables
without a process and another part with. This allows us to skip the
former on Apple Silicon, where lack of support for chained fix-ups
causes the test to fail.

The StringPrinter class was using a Process instance to read memory.
This automatically prevented it from working before starting the
program.
This patch changes the class to use the Target object for reading
memory, as targets are always available. This required moving
ReadStringFromMemory from Process to Target.
This is sufficient to make frame/target variable work, but further
changes are necessary for the expression evaluator. Preliminary analysis
indicates the failures are due to the expression result ValueObjects
failing to provide an address, presumably because we're operating on
file addresses before starting. I haven't looked into what would it take
to make that work.

Based on post-commit review discussion on
2bd84938470bf2e337801faafb8a67710f46429d with Richard Smith.
Other uses of forcing HasEmptyPlaceHolder to false seem OK to me -
they're all around pointer/reference types where the pointer/reference
token will appear at the rightmost side of the left side of the type
name, so they make nested types (eg: the "int" in "int *") behave as
though there is a non-empty placeholder (because the "*" is essentially
the placeholder as far as the "int" is concerned).
This was originally committed in 277623f4d5a672d707390e2c3eaf30a9eb4b075c
Reverted in f9ad1d1c775a8e264bebc15d75e0c6e5c20eefc7 due to breakages
outside of clang - lldb seems to have some strange/strong dependence on
"char [N]" versus "char[N]" when printing strings (not due to that name
appearing in DWARF, but probably due to using clang to stringify type
names) that'll need to be addressed, plus a few other odds and ends in
other subprojects (clang-tools-extra, compiler-rt, etc).

All these tests can just call lldbutil.run_to_source_breakpoint
instead of reimplementing it.

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.
