Deps: Replace androidx compose foundation with foundation layout

Removing the 'androidx.compose.foundation:foundation' dependency wasn't
enough by itself as the build was then failing. Adding the transient
'androidx.compose.foundation:foundation-layout' dependency was actually
required in order to make the build successful again.

FYI: It got introduced as part of this
(7d8d37c) commit, a part of
implementing placeholders in compose.

------------------------------------------------------------------------

This replacement was suggested by the dependency analysis report, see
below:

Unused dependencies which should be removed:
  implementation 'androidx.compose.foundation:foundation:1.7.5'
  ...

These transitive dependencies should be declared directly:
  ...
  implementation 'androidx.compose.foundation:foundation-layout:1.7.5'
  ...
