Change the behavior of --ignore-case and --multiline options for find (#16323)

Browse Source 
# Description

Changes the behavior of `--ignore-case` and `--multiline` options for
`find`, to make them more consistent between regex mode and search term
mode, and to enable more options for using find.

# User-Facing Changes

Search term mode is now case-sensitive by default.

`--ignore-case` will make the search case-insensitive in search term
mode. In regex mode, the previous behavior of adding a (?i) flag to the
regex is preserved.

`--multiline` will no longer add a (?m) flag in regex mode. Instead, it
will make the search not split multi-line strings into lists of lines.
