cdc6f8d728 Read and write a LC_NOTE "addrable bits" for addressing mask
This patch adds code to process save-core for Mach-O files which
embeds an "addrable bits" LC_NOTE when the process is using a
code address mask (e.g. AArch64 v8.3 with ptrauth aka arm64e).
Add code to ObjectFileMachO to read that LC_NOTE from corefiles,
and ProcessMachCore to set the process masks based on it when reading
a corefile back in.

Also have "process status --verbose" print the current address masks
that lldb is using internally to strip ptrauth bits off of addresses.

d9773c1b4e Reorg firmware corefile tests; add test for OS plugin loading
A little cleanup to how these firmware corefile tests are done; add
a test that loads a dSYM that loads an OS plugin, and confirm that
the OS plugin's threads are created.

78a1412845 Handle all standalone combinations of LC_NOTEs w/ & w/o addr & uuid
Fill out ProcessMachCore::DoLoadCore to handle LC_NOTE hints with
a UUID or with a UUID+address, and load the binary at the specified
offset correctly.  Add tests for all four combinations.  Change
DynamicLoaderStatic to not re-set a Section's load address in the
Target if it's already been specified.

2cedc44a92 Ignore DBGArchitecture from dsymForUUID's plist
When the architecture from the returned plist differs from the
architecture lldb will pick when loading the binary file, lldb will
reject the binary as not matching.  We are working with UUID's in
this case, so an architecture is not disambiguating anything; it
just opens this possibility for failing to load the specified binary.
Stop reading the architecture from the plist.

1bec6eb3f5 Add support for firmware/standalone LC_NOTE "main bin spec" corefiles
When a Mach-O corefile has an LC_NOTE "main bin spec" for a
standalone binary / firmware, with only a UUID and no load
address, try to locate the binary and dSYM by UUID and if
found, load it at offset 0 for the user.

Add a test case that tests a firmware/standalone corefile
with both the "kern ver str" and "main bin spec" LC_NOTEs.

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.
