If a wrong configuration.toml file is used by accidentally, runtime-rs
binary could run into panic because of unwrap().
This fixes the panic by returning errors instead of unwrap().

PR #8483 changed the location of the rust runtime config files to
`/etc/kata-containers/runtime-rs/`. However, if you haven't updated your
system to create that directory, attempting to create a container using
the rust runtime was giving the following cryptic message
(formatted for easier reading):
```
failed to handler message try init runtime instance
Caused by:
0: load config
1: load toml config
2: entity not found
```
Now, the message is as follows (again, reformatted for easier reading):
```
failed to handle message try init runtime instance
Caused by:
0: load config
1: load TOML config failed (tried [
\"/etc/kata-containers/runtime-rs/configuration.toml\",
\"/usr/share/defaults/kata-containers/runtime-rs/configuration.toml\",
\"/opt/kata/share/defaults/kata-containers/runtime-rs/configuration.toml\"
])
```

It is no longer necessary to be `root` to query the guest protection
(TDX) on `x86_64` systems, so drop the requirement.
> **Note:**

> This change drops the `nix` `Uid` import required for the `root` check.
> But at the same time it adds it for PPC64le since that implementation of

PR #8311 inadvertently broke the logging since no log messages below the
`Info` level are logged now, regardless of the requested log level.
Resolve the issue by storing the requested log level in the
`RuntimeComponentLevelFilter` and using that level in the `log()`
function, rather than hard-coding `Info` as the default where no entry
is found in the `FILTER_RULE` hashmap.

As the configuration files are different, we can safely remove those as
any new installation of the binary should also bring in the new
configurations.
This makes things less error-prone in the future, as we're ensuring that
the rust runtime will only be reading the rust configuration files.

The +fieldpath option, specific to gogoprotobuf, enabled dynamic field
access in protobuf messages, allowing nested fields to be accessed via
string paths.
This change is part of a larger effort to transition to the official Go
protobuf library for better maintainability and community support.
Upon review, no instances of dynamic field access were found in the
codebase, confirming that the feature is not in use.
By removing this unused feature, we simplify the build process and make
it easier to complete the transition away from gogoprotobuf.

Add the missing closing bracket to the output of the TDX details,
so rather than:
```bash
$ sudo kata-ctl env 2>/dev/null | grep available_guest_protection
available_guest_protection = "tdx (major_version: 1, minor_version: 0"
: ^
: Missing ')' !
```
... we now have:
```bash
$ sudo kata-ctl env 2>/dev/null | grep available_guest_protection
available_guest_protection = "tdx (major_version: 1, minor_version: 0)"
: ^
: Aha!
```

Allow Cloud Hypervisor to create a confidential guest (a TD or
"Trust Domain") rather than a VM (Virtual Machine) on Intel systems
that provide TDX functionality.
> **Notes:**
>
> - At least currently, when built with the `tdx` feature, Cloud Hypervisor
> cannot create a standard VM on a TDX capable system: it can only create
> a TD. This implies that on TDX capable systems, the Kata Configuration

> will detect this and display the following error:
>
> ```
> TDX guest protection available and must be used with Cloud Hypervisor (set 'confidential_guest=true')
> ```
>
> - This change expands the scope of the protection code, changing
> Intel TDX specific booleans to more generic "available guest protection"
> code that could be "none" or "TDX", or some other form of guest

This commit allows us to specify the huge page backend when enabling huge
page. Currently, we support two backends: thp and hugetlbfs, the default
is hugetlbfs.
To ensure backward compatibility, we introduce another configuration item
"hugepage_type" to select the memory backend, which is available only when
"enable_hugepages" is true. Besides, we add an annotation
"io.katacontainers.config.hypervisor.hugepage_type" to configure huge page
type per pod.

gogo.nullable is the main gogo.protobuf' feature used here. Since we are
trying to remove gogo.protobuf, the first reasonable step seems to be
remove this feature. This is a core update, and it will change how the
structs are defined. I could spot only a few places using those structs,
based on make check/build.

import_path is used as the default package when no input files specify
go_package. However, all the files we are currently building already
have a go_package definition, making this behavior both redundant and
error-prone.
Additionally, one of our files (types.pb.go) resides outside the grpc
directory, indicating that it's indeed ignored but also inconsistent.

Currently, the script searches for .proto files within $GOPATH/.
Consequently, modifications to a definition file in the current working
directory won't influence the output .pb.go if the directory is outside
of $GOPATH. For developers, it's more intuitive to alter the local
codebase than the version stored in $GOPATH.
With this modification, the generated .pb.go files will be relative to
the current working directory, removing the need to clone this project
under $GOPATH/src/github.com/kata-containers.
