[ruby-core:80451] [Ruby trunk Feature#13381] [PATCH] Expose rb_fstring and its family to C extensions

ruby-core #80451
Issue #13381 has been updated by eagletmt (Kohei Suzuki).
OK, I've read comments of #13077.
What do you think of renaming fstring to "deduped" string? "Deduped" strings are implicitly frozen.
- Rename `rb_fstring` to `rb_str_deduped`
- Rename `rb_fstring_new` to `rb_str_deduped_new`
- Rename `rb_fstring_cstr` to `rb_str_deduped_cstr`
- Rename `rb_fstring_enc_new` to `rb_enc_str_deduped_new`
- Rename `rb_fstring_enc_cstr` to `rb_enc_str_deduped_cstr`
- I think `enc` should come first for consistency

Feature #13381: [PATCH] Expose rb_fstring and its family to C extensions

Currently, C extensions cannot use fstrings. I'd like to use
`rb_fstring_cstr` instead of `rb_str_new_cstr` for static strings in C
extensions to avoid excess allocation.
I think there's several use cases.
