[heap] expand internal heap size for ECDSA (#5988)

Browse Source 
The ECDSA feature needs more heap to run because buffers for signing
and signature verification are dynamically allocated.

The number 2600 is the minimum (not precise) size to pass the
test_ecdsa unittest case. This is not revealed in CI tests because
DTLS is enabled (and thus we have much larger heap) for unittest
check.
