ompio file_read_all: relocate implementation from base to common

Move the default implementation of the read_all function used by some components
from fcoll/base to common/ompio, in order to resolve dependency problems with fcoll/base.
Re-introduce per-component read_all functions, which are however only stubs calling
the common/ompio implementation.

Tested with static and dynamic builds. Also ensured that the --disable-io-ompio flag
still works correctly.
