fix(esp_libc): provide picolibc timespec_get

Browse Source 
The Picolibc headers in the ESP-IDF v6.0 toolchain declare the C11
timespec_get API, but the corresponding archives do not define it.
Provide the missing compatibility implementation through esp_libc
and cover valid and invalid time bases.
