add compiler/parallel/tcltk R libraries included in base installation to extensions in R 4.x easyconfigs using foss toolchain

[boegel]

(created using eb --new-pr)

Including these additional libraries in exts_list doesn't actually affect the installation at all, since they're always installed, even when not listed explicitly as extension.

The main motivation for doing this is to ensure that base R libraries that are listed as a required dependency for R libraries from CRAN are included in exts_list, which is required to be able to install the extensions in parallel (cfr. easybuilders/easybuild-framework#3667 and easybuilders/easybuild-easyblocks#2408).

(I'll open separate PRs for R easyconfigs using a fosscuda toolchain, and for older versions, to facilitate submitting test reports)
