mbedtls_config: add new MBEDTLS_PK_PARSE_EC_COMPRESSED symbol
This includes also:
- auto enabling ECP_LIGHT when MBEDTLS_PK_PARSE_EC_COMPRESSED is
defined
- replacing ECP_LIGHT guards with PK_PARSE_EC_COMPRESSED in pkparse
- disabling PK_PARSE_EC_COMPRESSED in tests with accelarated EC curves
(it get disabled also in the reference components because we want
to achieve test parity)
- remove skipped checks in analyze_outcomes.py
