[Core][Benchmark] Add benchmarks for Table GetValue and GetDerivative

[loumalouomega]

📝 Description

This PR introduces performance benchmarks for the Table::GetValue and Table::GetDerivative methods.

The benchmarks are designed to measure the performance of these functions across various table sizes: 5, 10, 20, 200, 2000, and 20000 elements.

For each test:

• A Table<double, double> is populated with sorted data, where X values are i*0.1 and Y values include a small sinusoidal variation.
• A number of lookup X values (5 times the table size) are generated. These lookup values are distributed such that 20% are below the table's minimum X value, 20% are above the table's maximum X value, and the remaining 60% are within the table's X range. This aims to test edge cases and typical usage.
• The GetValue or GetDerivative method is called repeatedly with these lookup values.
• volatile is used for the sum of results to prevent the compiler from optimizing away the core lookup operations.

These benchmarks will help in monitoring and improving the performance characteristics of the Table class. (My experiments have been futile, but the benchmark is OK)
