[libc] separate out TLSFTable to its own header and add unit tests

Address code review comments:
- Extract TLSFTable abstraction into tlsf_table.h to encapsulate occupancy bitmaps and bin sizing formulas without changing core allocator algorithm logic or O(1) fast paths.
- Add exhaustive unit tests in tlsf_table_test.cpp.
- Remove redundant {} default member initializers from structured list classes.
- Format heap-related files with clang-format.
