Be able to extract value of components in UI

[cicdguy]

In tmc (utils.R) we have to break encapsulation to see what values are selected in the UI

extract_input <- function(varname, dataname, filter = FALSE) {
  if (filter) {
    paste0(varname, "-dataset_", dataname, "_singleextract-filter1")
  } else {
    paste0(varname, "-dataset_", dataname, "_singleextract-select")
  }
}

NEST/teal.modules.general/issues/905 and possibly other shared code in the future.

This issue is to allow this behaviour without breaking encapsulation (it may involve adapting what we have e.g. a flag as to whether to return what we do now, or also the raw selected values, it may involve replacing with a simple select component in teal.devel to be created which doesn't interact with data) and then to create an issue in tmc to fix this.

NEST/teal.devel/issues/404 at the same time

Please note that extract_input method is present in teal.devel, teal.modules.clinical (public) and teal.modules.general. Please resolve these duplicates

So I believe we can do this now see e.g. here but some comments:

1. We don't always do it e.g. https://github.com/insightsengineering/teal.modules.clinical/blob/main/R/tm_t_pp_laboratory.R#L397-L402
2. It's quite clunky to get this information out
3. Sometimes we actually want the output from the merge instead - i.e https://github.com/insightsengineering/teal.modules.clinical/blob/main/R/tm_t_coxreg.R#L824 which is very very clunky and it's not obvious to module developers which they should be using when...
