newlib: Provide library name for ROM libc object files linked as PSRAM workarounds

Browse Source 
Works around bug reported on forums where any source file ending in *lock.c or *creat.c
was being linked to IRAM.

https://esp32.com/viewtopic.php?f=13&t=8909&p=37362#p37362

Also moves all related functionality to newlib component.
