Disable commit timestamps during bootstrap

Attempting to use commit timestamps during bootstrapping leads to an
assertion failure, that can be reached for example with an initdb -c
that enables track_commit_timestamp.  It makes little sense to register
a commit timestamp for a BootstrapTransactionId, so let's disable the
activation of the module in this case.

This problem has been independently reported once by each author of this
commit.  Each author has proposed basically the same patch, relying on
IsBootstrapProcessingMode() to skip the use of commit_ts during
bootstrap.  The test addition is a suggestion by me, and is applied down
to v16.
