Implement EC_GROUP and EC_POINT as sub-modules of ec module (#336)

* Initial plan

* Add EC_GROUP and EC_POINT standalone modules with comprehensive tests

Co-authored-by: zhaozg <542599+zhaozg@users.noreply.github.com>

* Complete EC_GROUP and EC_POINT implementation with all tests passing

* Add CodeQL build artifacts to gitignore

* Add point operations to EC_GROUP and fix tostring format

- Added point operations (point_new, point_dup, point_equal, point2oct, oct2point, point2bn, bn2point, point2hex, hex2point, affine_coordinates, generate_key) to EC_GROUP methods in group.c
- Fixed EC_POINT tostring to include "openssl." prefix (changed from "ec_point: %p" to "openssl.ec_point: %p")
- Added group.lua and point.lua to test/test.lua
- All 128 tests now pass (16 group tests + 23 point tests + 89 existing tests)

* Refactor ec.c to reuse code from group.c and point.c

- Made helper functions in group.c non-static (openssl_to_group_asn1_flag, openssl_push_group_asn1_flag, openssl_to_point_conversion_form, openssl_push_point_conversion_form)
- Removed duplicate helper functions from ec.c that now exist in group.c
- Created ec_group_point.h header to export needed functions
- ec.c now reuses functions from group.c and point.c instead of duplicating them
- All 128 tests pass (16 group + 23 point + 89 existing)

* Restructure EC modules: include group.c/point.c in ec.c as sub-modules

- group.c and point.c are now included directly in ec.c (not compiled separately)
- All functions in group.c and point.c are now static
- group and point are registered as ec sub-modules (openssl.ec.group, openssl.ec.point)
- Removed group.o and point.o from Makefile and CMakeLists.txt
- Removed standalone luaopen_grou... (continued)
