Fix undefined references build error on Windows (x64) (#3168)

We should emit function symbols for these jerry-core functions:
- ecma_compare_ecma_strings is used by test-stringbuilder.c
- ecma_is_value_number is used by test-literal-storage.c
- ecma_date_time_within_day is used by test-date-helpers.c
- jmem_heap_alloc_block is used by test-jmem.c
- jmem_heap_free_block is used by test-jmem.c
- jmem_pools_alloc is used by test-poolman.c
- jmem_pools_free is used by test-poolman.c
