[PATCH v1 2/4] read-cache: move 'ce_mode_from_stat()' to 'read-cache.c'

[Tian Yuchen <cat@malon.dev>]

The ce_mode_from_stat() function is declared as a static inline function
in 'read-cache.h'. As we want to migrate configuration variables, this
helper function will need access to corresponding repository-specific
configuration logic. Move the implementation to 'read-cache.c' to
cleanly encapsulate its dependencies.

Note that the 'extern int trust_executable_bit, has_symlinks;' line is
discarded because it's not necessary when the function lives in
"read-cache.c".
