Upon `terminal_enter`, `mapped_ctrl_c` is set in order to avoid `CTRL-C`
interrupts (which is proxied to the terminal process instead), `os_inchar`
will then test `mapped_ctrl_c` against `State` and set `ctrl_c_interrupts=false`
which prevents `process_ctrl_c` from setting `got_int=true` in a terminal
state.
However, if `got_int` is set outside of `process_ctrl_c`, e.g. via
`interrupt()`, this will hang the neovim process as `terminal_execute` will
enter an endless loop as `got_int` will never be cleared causing `safe_vgetc`
to always return `Ctrl_C`.
A minimal example reproducing this bug:
```vim
:autocmd TermEnter * call timer_start(500, {-> interrupt()})
:terminal
:startinsert
```
To fix, we make sure `got_int` is cleared inside `terminal_execute` when
it detects `Ctrl_C`.
Closes #20726
