Hi,

Some fixes in #63731 made Japanese input so slow even on my Xeon 3.2Gx2 with HT machine.

The newly attached patch does:
- Remove preedit_len and add
im_preedit,im_preedit_attrs,im_preedit_cursor to e-text.h
- Fix memory leak in e_text_preedit_changed_cb()
- Reduce the redundant gtk_im_context_get_preedit_string() call
- Remove slow codes from e_text_draw()
- Use gchar* instead of GString
- Remove pango_layout_*() funcs from preedit handling to speed up
- Move gtk_im_context_filter_keypress() funcs to
  GDK_KEY_PRESS section. Because the keypress func
  doesn't make sense in GDK_KEY_RELEASE section.

And now it works for me.
Japanese input feature is indispensable on mail client, so this fix is
important for Japanese.

Thank you.
