entity-manager: fix type for schema directory

Change the type of schema directory from
`constexpr const char*` to `std::filesystem::path` and pass it through
the appropriate functions instead of declaring in the header.

This avoids e.g. testcases gaining a dependency on PACKAGE_DIR symbol
and allows them to pass in a different directory for schemas, as the
package is usually not installed in a development / ci workflow.

Tested:

EM starts normally, configuration is loaded as expected and appears on
DBus.

Previously, matched names were not being replaced

Remove implicit conversions

Implicit conversions are something that nlohmann library itself is a bad
default, and 3 years ago threatened to change the default. These
implicit conversions cause a number of crashes that are hard to
reproduce, because they throw an uncaught exception.

Update the code to be able to do no more implicit conversions.

Tested: Entity-manager launches and runs. Items are detected correctly
and show up on dbus. Unit tests pass.

Flat map all the things

In an earlier commit, entity-manager gained required dependency
on std::flat_map. This means that EM can only compile with gcc-15,
which the project only recently moved to. Rather than move backwards,
port forward all uses of boost flat_map and flat_set to their std
equivalents.

Tested: entity-manager launches and enumerates devices on
gb200-obmc.

Probed path of board 'probed_by' inventory board path.
Inventory board path 'probing' probe path.
A probe path can be valid statement found in the 'Probe' statement of a
EM configuration.

This change could require testing on real hardware from other reviewers
and maintainers to make sure, the feature works as intended.

Tested on QEMU/Yosemite4 with EEPROM data added to QEMU source code.
This allows loading configurations without changing the probe
statements.

entity-manager: use PDI constants for inventory

Use PDI constants to create inventory interfaces, where possible. This
helps to make the code more readable and guarantees the interfaces which
are directly created from a PDI constant actually exist.

Also use the decorator asset interface PDI definition to query asset
information.

Tested: on Tyan S8030

Inventory interfaces are created as before
```
busctl introspect xyz.openbmc_project.EntityManager /xyz/openbmc_project/inventory/system/board/Tyan_S8030_Baseboard

entity-manager: use PDI constants for Host State

PDI already defines interface name and path namespace, use that instead
of duplicating it here.

Using the interface variable for service name since service name is not
defined in PDI and it's the same.

Defining default service name in [1].

Don't handle leftover template vars for "Probe" string

Don't handle leftover template vars for "Probe" string

As "Probe" string does not contain any template variable, we should not
check for leftover template variables in it after performing template
variable replacement which can mistakenly treat the regex token "$" as a
template variable.

This commit also skips handling leftover template variables for
"Exposes" object when the replacement is performed on the record for the
first time. The handling will be done when the replacement is targeted
for "Exposes" object later.

Tested on configurations with regex patterns in Probe string and and on
meta's fan boards that have math operations for more than 2 template
variables in the same JSON pair value. e.g:

```
"in0_Name": "FCB_$bus % 2 FAN_$bus % 2 * 2 VOLT_V",
```

use phosphor-logging

Migrate all instances of std::cerr and std::cout to phosphor-logging
such as lg2::error, lg2::info, lg2::debug, ...

The use of modern logging infrastructure helps with development since
additional logging levels such as `debug` and `warning` are available.

Migrating the remaining logging calls helps to make the code more
readable and uniform.

Tested: Inspection, and on Tyan S8030

Restarted EM with patch applied.
Logs appear as usual.
