Update on "Install libcpp from release package other than apt-get"

A few changes

1. Use the release package from https://releases.llvm.org/ to install libcpp, so we can install from different linux in addition to Ubuntu
2. Seperate out the qnn version and the url to a seperate file, for better versin management in the future

+
+## Overview
+
+The Executorch Benchmark Tooling provides a suite of utilities designed to:
+
+- Fetch benchmark data from HUD Open API for specified time ranges
+- Clean and process data by filtering out failures
+- Compare metrics between private and public devices with matching configurations
+- Generate analysis reports in various formats (CSV, Excel, JSON)
+- Support filtering by device pools, backends, and models
+
+This tooling is particularly useful for performance analysis, regression testing, and cross-device comparisons.
+
+## Installation
+
+Install dependencies:
+
+```bash
+pip install -r requirements.txt
+```
+
+## Tools
+
+### get_benchmark_analysis_data.py
+
+This script is mainly used to generate analysis data comparing private devices with public devices using the same settings.
+
+It fetches benchmark data from HUD Open API for a specified time range, cleans the data by removing entries with FAILURE indicators, and retrieves all private device metrics along with equivalent public device metrics based on matching [model, backend, device_pool_names, arch] configurations. Users can filter the data by specifying private device_pool_names, backends, and models.
+
+#### Quick Start
+
+```bash
+# generate excel sheets for all private devices with public devices using the same settings
+python3 .ci/scripts/benchmark_tooling/get_benchmark_analysis_data.py \
+  --startTime "2025-06-11T00:00:00" \
+  --endTime "2025-06-17T18:00:00" \
+  --outputType "excel"
+
+# generate the benchmark stability analysis
+python3 .ci/scripts/benchmark_tooling/analyze_benchmark_stability.py \
+--primary-file private.xlsx \
+--reference-file public.xlsx
+```
+
+#### Command Line Options
+
+##### Basic Options:
+- `--startTime`: Start time in ISO format (e.g., "2025-06-11T00:00:00") (required)
+- `--endTime`: End time in ISO format (e.g., "2025-06-17T18:00:00") (required)
+- `--env`: Choose environment ("local" or "prod", default: "prod")
+- `--no-silent`: Show processing logs (default: only show results & minimum logging)
+
+##### Output Options:
+- `--outputType`: Choose output format (default: "print")
+  - `print`: Display results in console
+  - `json`: Generate JSON file
+  - `df`: Display results in DataFrame format: `{'private': List[{'groupInfo':Dict,'df': DF},...],'public':List[{'groupInfo':Dict,'df': DF}]`
+  - `excel`: Generate Excel files with multiple sheets, the field in first row and first column contains the JSON string of the raw metadata
+  - `csv`: Generate CSV files in separate folders, the field in first row and first column contains the JSON string of the raw metadata
+- `--outputDir`: Directory to save output files (default: current directory)
+
+##### Filtering Options:
+
+- `--device-pools`: Filter by device pool names (e.g., "apple_iphone_15_private", "samsung_s22_private")
+- `--backends`: Filter by specific backend names (e.g.,"xnnpack_q8")
+- `--models`: Filter by specific model names (e.g., "mv3", "meta-llama/Llama-3.2-1B-Instruct-SpinQuant_INT4_EO8")
+
+#### Example Usage
+
+Filter by multiple private device pools and models:
+```bash
+# This fetches all private table data for models 'llama-3.2-1B' and 'mv3'
+python3 .ci/scripts/benchmark_tooling/get_benchmark_analysis_data.py \
+  --startTime "2025-06-01T00:00:00" \
+  --endTime "2025-06-11T00:00:00" \
+  --device-pools 'apple_iphone_15_private' 'samsung_s22_private' \
+  --models 'meta-llama/Llama-3.2-1B-Instruct-SpinQuant_INT4_EO8' 'mv3'
+```
+
+Filter by specific device pool and models:
+```bash
+# This fetches all private iPhone table data for models 'llama-3.2-1B' and 'mv3',
+# and associated public iPhone data
+python3 .ci/scripts/benchmark_tooling/get_benchmark_analysis_data.py \
+  --startTime "2025-06-01T00:00:00" \
+  --endTime "2025-06-11T00:00:00" \
+  --device-pools 'apple_iphone_15_private' \
+  --models 'meta-llama/Llama-3.2-1B-Instruct-SpinQuant_INT4_EO8' 'mv3'
+```
+
+#### Working with Output Files CSV and Excel
+
+You can use methods in `common.py` to convert the file data back to DataFrame format. These methods read the first row in CSV/Excel files and return results with the format `list of {"groupInfo":DICT, "df":df.Dataframe{}}`.
+
+```python
+import logging
+logging.basicConfig(level=logging.INFO)
+from .ci.scripts.benchmark_tooling.common import read_all_csv_with_metadata, read_excel_with_json_header
+
+# For CSV files (assuming the 'private' folder is in the current directory)
+folder_path = './private'
+res = read_all_csv_with_metadata(folder_path)
+logging.info(res)
+
+# For Excel files (assuming the Excel file is in the current directory)
+file_path = "./private.xlsx"
+res = read_excel_with_json_header(file_path)
+logging.info(res)
+```
+
+#### Python API Usage
+
+To use the benchmark fetcher in your own scripts:
+
+```python
+from .ci.scripts.benchmark_tooling.get_benchmark_analysis_data import ExecutorchBenchmarkFetcher
+
+# Initialize the fetcher
+fetcher = ExecutorchBenchmarkFetcher(env="prod", disable_logging=False)
+
+# Fetch data for a specific time range
+fetcher.run(
+    start_time="2025-06-11T00:00:00",
+    end_time="2025-06-17T18:00:00"
+)
+
+# Use the output_data method for flexible output
+results = fetcher.output_data(output_type="excel", output_dir="./results")
+```
+
+## Running Unit Tests
+
+The benchmark tooling includes unit tests to ensure functionality.
+
+### Using pytest for unit tests
+
+```bash
+# From the executorch root directory
+pytest -c /dev/null .ci/scripts/tests/test_get_benchmark_analysis_data.py
+```
