ORT perf test support for plugin EP (#25374)
### Description
Add support for onnxruntime_perf_test to register plugin EP dll and run
plugin EP.
As support for plugin execution providers (EPs) requires additional
options and most single-character options have already been used,
multi-character options are now necessary to ensure clarity and
readability. Therefore, support for `Abseil flags` is added, which
enables multi-character options and provides cross-platform
compatibility.
**New options:**
- `--plugin_ep_libs [registration names and libraries]` Specifies a list
of plugin execution provider (EP) registration names and their
corresponding shared libraries to register.
[Usage]: `--plugin_ep_libs "plugin_ep_name_1|plugin_ep_1.dll
plugin_ep_name_2|plugin_ep_2.dll ... "`
- `--plugin_eps [Plugin EPs]` Specifies a semicolon-separated list of
plugin execution providers (EPs) to use.
[Usage]: `--plugin_eps "plugin_ep_1;plugin_ep_2;... "`
- `--plugin_ep_options [EP options]` Specifies provider options for each
EP listed in --plugin_eps. Options (key-value pairs) for each EP are
separated by space and EPs are separated by semicolons.
[Usage]:
`--plugin_ep_options "ep_1_option_1_key|ep_1_option_1_value
...;ep_2_option_1_key|ep_2_option_1_value ...;..."` or
`--plugin_ep_options ";ep_2_option_1_key|ep_2_option_1_value ...;..."`
or
`--plugin_ep_options "ep_1_option_1_key|ep_1_option_1_value
...;;ep_3_option_1_key|ep_3_option_1_value ...;..."`
- `--list_ep_devices` Prints all available device indices and their
properties (including metadata). This option makes the program exit
early without performing inference.
- ` --select_ep_devices [list of device indices]` A semicolon-separated
list of device indices to add to the session and run with.
**Usage:**
1. Use `--plugin_ep_libs` and `--list_ep_devices` to list all the
devices.
````sh
--list_ep_devices --plugin_ep_libs "TensorRTEp|C:\TensorRTEp.dll example_ep|C:\example_plugin_ep.dll"
````
It will print the devices info
````
===== EP device id 0 ======
name: CPUExecutionProvider
vendor: Microsoft
metadata:
version: 1.23.0
===== EP device id 1 ======
name: example_ep
vendor: Contoso
metadata:
supported_devices: CrackGriffin 7+
version: 0.1.0
===== EP device id 2 ======
name: TensorRTEp
vendor: Nvidia
metadata:
gpu_type: data center
version: 0.1.0
````
2. Use `--select_ep_devices` to select the device by index. And add
`--plugin_eps` to specify the EP name. The EP name should match the name
when ep library passes in to create the ep factory.
````sh
--plugin_ep_libs "TensorRTEp|C:\TensorRTEp.dll" --select_ep_devices 2 --plugin_eps TensorRTEp -r 1 C:\mul_op\mul_1.onnx
````
3. Or simply use `-e` to specify the EP name. ORT perf test will add all
the devices created by the plugin EP.
The EP name should match the name when ep library passes in to create
the ep factory.
````sh
--plugin_ep_libs "TensorRTEp|C:\TensorRTEp.dll" --plugin_eps TensorRTEp -r 1 C:\mul_op\mul_1.onnx
````
