Hyukjin Kwon 9106671b36 GH-48980: [C++] Use COMPILE_OPTIONS instead of deprecated COMPILE_FLAGS (#48981) ...

### Rationale for this change

Arrow requires CMake 3.25 but was still using deprecated `COMPILE_FLAGS` property. Recommanded to use `COMPILE_OPTIONS` (introduced in CMake 3.11).

### What changes are included in this PR?

Replaced `COMPILE_FLAGS` with `COMPILE_OPTIONS` across `CMakeLists.txt` files, converted space separated strings to semicolon-separated lists, and removed obsolete TODO comments.

### Are these changes tested?

Yes, through CI build and existing tests.

### Are there any user-facing changes?

No.
