[C API] Implement memory estimation functions for index build and search

[rfsaliev]

This pull request introduces a set of enhancements to the C API and internal implementation to support memory usage estimation for index building and search operations. The primary focus is on adding new estimation functions, implementing the underlying logic for various data builders, and integrating these features with both static and dynamic Vamana index types. The changes also include updates to the build system to incorporate new source files.

New C API for Memory Estimation:

• Added several new API functions to estimate memory usage for index building and search operations, including support for both static and dynamic indices, as well as search queries. These functions allow users to obtain detailed memory breakdowns before performing expensive operations.

Implementation of Estimation Logic:

• Implemented estimate_size methods for all major data builders (SimpleDataBuilder, LVQDataBuilder, LeanVecDataBuilder, SQDataBuilder) to provide accurate memory usage estimation based on builder configuration, number of vectors, and dimension. [1] [2] [3] [4]
• Created data_builder.cpp and corresponding header to dispatch and specialize estimation logic for different data types and block sizes. [1] [2]

Integration with Vamana Index Types:

• Added dispatcher functions to estimate memory usage for both static and dynamic Vamana indices, providing structured breakdowns of graph, data, and metadata memory requirements. [1] [2] [3] [4]

Build System and Dependency Updates:

• Updated CMakeLists.txt to include the new data_builder.cpp source file, ensuring the new logic is compiled and linked.
• Added necessary includes and dependencies in implementation files to support the new estimation features. [1] [2] [3]

Summary of Most Important Changes:

1. API Additions

• Added new C API functions for estimating memory usage of index building and search operations, including dynamic and static variants.

2. Memory Estimation Logic

• Implemented estimate_size methods for all major data builders to enable accurate memory usage estimation. [1] [2] [3] [4]
• Created data_builder.cpp and header to centralize and dispatch estimation logic for various data types/blocking strategies. [1] [2]

3. Vamana Index Integration

• Added dispatcher functions for memory estimation of static and dynamic Vamana indices, including detailed breakdowns. [1] [2] [3] [4]

4. Build and Dependency Updates

• Included new source files in the build system and updated includes for proper compilation and linkage. [1] [2] [3] [4]
