When context.Context was new, APIs using it arrived sporadically and so
the Go team introduced context.TODO() as an explicit way to say "I need a
context but I don't yet have a useful one to provide".
It took quite a while for there to be an established pattern for contexts
in tests, but now there is finally testing.T.Context which returns a
context that gets cancelled once the test is complete, and so that's a good
parent context to use for all contexts belonging to a test case.
This commit therefore mechanically replaces every use of context.TODO in
our test cases throughout the codebase with a call to t.Context instead.
There were a small number of tests that were using a mixture of
context.TODO and context.Background as placeholders and so those are also
updated to use t.Context consistently. There are probably still some
remaining uses of context.Background in our tests, but we'll save those
for another day.
As of this commit there are still various uses of context.TODO left in
_non-test_ code, but we need to take more care in how we update those so
those are intentionally excluded here.

This is part of a general effort to move all of Terraform's non-library
package surface under internal in order to reinforce that these are for
internal use within Terraform only.
If you were previously importing packages under this prefix into an
external codebase, you could pin to an earlier release tag as an interim
solution until you've make a plan to achieve the same functionality some
other way.
