fix(mbedtls): fix undefined esp_mbedtls_mem_calloc/free at link time

Browse Source 
platform.c (compiled into the 'builtin' archive) calls
esp_mbedtls_mem_calloc and esp_mbedtls_mem_free directly by name via
the MBEDTLS_PLATFORM_STD_CALLOC/FREE macros in esp_config.h.
Previously, esp_mem.c was compiled into the 'tfpsacrypto' archive, which
appears after 'builtin' in the link command, causing the linker to fail
with undefined reference errors when 'builtin' was processed first.

Moving esp_mem.c into 'builtin' to assure that the function used by
esp_mbedtls_mem_calloc and esp_mbedtls_mem_free are available when
pltform.c is linked.
