meson: Fix local build of the settings_gen target

Currently local meson build fails with the following error:
"""

FAILED: settings_manager.hpp
<...>/env/bin/python3 ../settings.py -i ../settings_example.yaml
<...>
ModuleNotFoundError: No module named 'sdbusplus'
"""
This is happening because 'settings_manager.mako.hpp' from the
'settings_gen' target refers to python modules from the external
'sdbusplus' project. Therefore in case of a local build it is
necessary to provide search path to the relevant sdbusplus subproject
folder. Fix this with the help of 'PYTHONPATH' environment variable.

Tested:
Both local meson build and Yocto build are finished successfully.

"""

Since cereal requires boost only for the sandbox build and this
functionality is not needed, add option to skip building performance
sandbox comparison to solve the issue.

Tested:
"meson setup build" no longer fails with the cereal error.

meson_options.txt: Support for reading options from meson.options

Support has been added for reading options from meson.options instead
of meson_options.txt[1]. These are equivalent, but not using the .txt
extension for a build file has a few advantages, chief among them
many tools and text editors expect a file with the .txt extension to
be plain text files, not build scripts.

Convert version 1 files to version 2 on startup

When reading in persisted property values from their files, check the
version number the file was saved in. If that version is less than the
first version using name/value pairs, then rewrite the file using the
latest version.

This is done so that it removes the possibility of the problem described
in openbmc/phosphor-settingsd/#16 of occurring in the future, which is
where if a new property is added it gets set to another property's
value.

This also creates functions for the serializing and deserializing so the
code to do it just needs to be in one place.

Note that if a version of code runs from when before NVP support was
added, it can still read files saved with the new version so this change
is backwards compatible.

Use named values when serializing

As described by openbmc/phosphor-settingsd#16, the code has a problem
when a new D-Bus property is added to a settings object that has a
modified property, meaning it has been serialized to file. This is
because the file doesn't say which property the value is meant for - the
fields are only named value0, value1, etc. So if the new property is
alphabetically before the original property, the code will read the
value0 value into the new property though it was meant to be for the
original one.

To fix this, start using cereal's Name/Value Pair (NVP) feature, with
the field names named after the property, like:
"QuiesceOnHwError": true

This requires the cereal version to bump from 1 to 2. When saving, the
code will always write using version 2 using NVPs. When loading it will
check the version in the file and if it was 1 it will read it using the
original non-NVP method, otherwise it will use the NVP method.

Example generated load and save functions:

```
template<class Archive>
void save(Archive& a,
const Impl& setting,
[[maybe_unused]] const std::uint32_t version)
{
a(cereal::make_nvp("AutoReboot", setting.autoReboot()));
}

template<class Archive>
void load(Archive& a,
Impl& setting,
const std::uint32_t version)
{
decltype(setting.autoReboot()) AutoReboot{};

if (version < CLASS_VERSION_WITH_NVP)
{
a(AutoReboot);
}
else
{
try
{
a(CEREAL_NVP(AutoReboot));
}
catch (const cereal::Exception& e)
{
std::cerr << "Could not restore property AutoReboot on /xyz/openbmc_project/control/host0/auto_reboot, "
<< "setting to default value.\n";
AutoReboot = true;
}
}

setting.autoReboot(AutoReboot);
}
```

This does require that the property names be unique across all
interfaces on that object path. So far that isn't an issue for anything
I've seen, and there is a check in the code that will cause a compile
failure if that occurs. If necessary, support could be added for this
but it didn't seem necessary as that is fairly unlikely.

Now if a new property is added to an object path with existing
serialized data, the code can see that that field isn't in the file and
will just initialize that property to the default value given in the
YAML.

If the version of code before this commit is applied to a system after
this code has already been run, it is still able to read in the values
even though they have real names instead of the valueN ones since other
than the name they are still in the same order and format.

Use relative path to append path

The path append behavior changed between std::experimental and
std::filesystem, appending an absolute path (path with a leading slash)
replaces the path instead of appending to it, therefore need to use the
relative path (path without the leading slash) when appending.

The issue was that directories were attempted to be created on "/xyz/.."
instead of "SETTINGS_PERSIST_PATH/xyz/..", causing the settings manager
to fail with:
what(): filesystem error: cannot create directories: Read-only file
system [/xyz/openbmc_project/control/host0]

Tested: Verified this error is not seeing when making redfish calls.
Also verified the generated build/settings_manager.hpp file uses either
the relative path or the xyz path doesn't have the leading slash:
p /= path.relative_path();
path = fs::path(SETTINGS_PERSIST_PATH) / "xyz/openbmc_project/control/host0/TPMEnable";
