tests: Migrate to placement_new from reinterpret casting

reinterpret_cast is prohibited by the C++ core guidelines because
it takes the behavior outside the language definition and gives
problems with type safety. Placement-new on the other-hand allows
to control the object storage while still properly instantiating
an object,keeping the behavior inside the C++ language
specification.

Move dbus_to_terminus_effecter code to platform-mc

In the current state , pldm build breaks when attempting to perform
a debug-optimized build (`-O2` optimization), leading to the following
linker error:

```
undefined reference to `pldm::platform_mc::TerminusManager::getActiveEidByName
(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)'
```

This issue is not encountered in the CI environment, as CI uses the
`-Og` optimization flag, which does not aggressively inline functions.
Consequently, the reference to `getActiveEidByName()` is resolved
without issue. However, when building the project with default
optimizations (debugoptimized [-O2]), the build fails because the
linker cannot resolve the reference to `getActiveEidByName()`, which is
inlined by the compiler.

To address this problem, there are three potential solutions:

1. Prevent Inlining of the Function:
We could use `__attribute__((noinline))` to prevent the compiler
from inlining `getActiveEidByName()`.

2. Move Source Files into `libpldmresponder`:
We could move the `platform-mc/manager.cpp` and
`platform-mc/terminus_manager.cpp` files into the `libpldmresponder`
so the compiler can resolve the reference directly within the
library.

3. Migrate `dbus_to_terminus_effecter.cpp` to the `platform-mc` folder:

The most appropriate solution appears to be migrating the
`dbus_to_terminus_effecter.cpp` file into the `platform-mc` directory.
This file is not inherently tied to `libpldmresponder` but functions as
a requester. Additionally, there are existing community patches that
allow the system to scale from a single host terminus to multiple
terminii, further justifying this move. So, solution #3 is the most
fitting at this stage. By relocating the `dbus_to_terminus_effecter`
code to the `platform-mc` folder, we can ensure proper modularity,
while also resolving the build issue in a clean and scalable manner.

Tested By:
1. meson build -Doptimization=2 works fine with the patchset.

platform-mc: Defer adding sensor objects from PDRs

After all PDRs retrieved from the other terminus are parsed into pdr
structs. They will be processed further to create sensor objects (e.g
via `addNumericSensor` function for Numeric Sensors).

During this phase for one sensor, sensor name is achieved (may enlist
Sensor Aux Name PDRs), and NumericSensor object is constructed.
Sensor object construction involves parsing pdr struct elements into
sensor class variables, D-Bus interface initialization and many calls
to set D-Bus object properties.

They are actually not blocking actions, but as it continuously loops
through sensor PDRs in `parseTerminusPDRs` to add sensors, they take
too much time and prevent BMC from processing events coming from other
termini. Not to mention the adding of new sensor types in the future
and the increase in sensor numbers, the total time will be large, while
this is not a primary task in the initialization phase of a terminus.

This commit defers `addNumericSensor` and `addCompactNumericSensor`
calls using sdeventplus::source::Defer event source, instead of
continuously calling them while looping through the sensor PDRs, to let
events coming from other termini break in and be processed by BMC.

Tested:

While BMC is getting, parsing sensor PDRs and creating sensor objects
from those PDRs, events can still be received from the other termini.

platform-mc: Handle `Connectivity` propertiesChanged signal

From Mctp codeConstruct version 2.0 [1], mctpd supports `.Connectivity`
property under `au.com.CodeConstruct.MCTP.Endpoint` interface of the
endpoint. This commit handles the propertiesChanged signal from this
interface, and updates the Availability of the MCTP Endpoint accordingly
in the source to enable or disable message sending/receiving via that
endpoint of the terminus.

[1] https://github.com/CodeConstruct/mctp/blob/v2.0/docs/endpoint-recovery.md#proposed-design

When the discovery process first starts, it will only handle the
endpoints that have `Available` `.Connectivity`. It lets the
propertiesChanged signal trigger the adding of the endpoints when they
are back to` Available`.

On interfaceAdded signal, it assumes that mctpd only publishes available
endpoints to D-Bus, so it adds the endpoints to the terminus anyway.

Tested:
1. Enable `unsafe-writable-connectivity` option in PACKAGECONFIG of mctp
recipe.
2. After PLDM discovers all the endpoints, write `Degraded` to
`.Connectivity` of one of the endpoint.
3. Write it back to `Available` to see how message is stopped from being
sent/received via the endpoint.

platform-mc: Support GetPLDMVersion

`GetPLDMCommands` in DSP0240 v1.1.0 requires the PLDM supported type
version. In the current implementation, when detecting new MCTP
endpoint, `pldmd` always send `0xff 0xff 0xff 0xff` version to
`GetPLDMCommand` in discovery steps with the assumption that the
terminus will response for the request with any version of PLDM type.

Some termini don't accept `0xff 0xff 0xff 0xff` as input
version to `GetPLDMCommands` command because value `0xff` only has
meaning `A value of 0xFF in the "update" field indicates that the field
to be ignored.` in the `Section 12.6.1 Version field encoding` in `MCTP
Base spec` DSP0236 v1.3.1 but not in `PLDM base spec` DSP0240 v1.1.0
where `GetPLDMCommand` is detailed.

Support sending `GetPLDMVersion` from the supported PLDM types of one
terminus in the `discovery step` to get the PLDM version. And use that
version as input for `GetPLDMCommands` of that PLDM types to get
the supported PLDM commands.
