Allow configuration of read timeouts at compile-time

Introduces compile-time constants
- MBEDTLS_SSL_CONF_READ_TIMEOUT
- MBEDTLS_SSL_CONF_HS_TIMEOUT_MIN
- MBEDTLS_SSL_CONF_HS_TIMEOUT_MAX
which allow to configure the read timeouts and
minimum/maximum handshake timeout at compile time.

Impact on code-size:

|  | GCC 8.2.1 | ARMC5 5.06 | ARMC6 6.12 |
| --- | --- | --- | --- |
| `libmbedtls.a` before  | 23147 | 23781 | 26703 |
| `libmbedtls.a` after | 23131 | 23753 | 26673 |
| gain in Bytes | 16 | 28 | 30 |
