WL #3670: Compile-time option to remove GRANT-related startup options

- configure --disable-grant-options defines DISABLE_GRANT_OPTIONS
- configure.js/cmake also updated
- if DISABLE_GRANT_OPTIONS is defined, mysqld no longer recognizes:
  --bootstrap
  --init-file
  --skip-grant-tables

Scripts which rely on those three options are modified to check the environment for MYSQLD_BOOTSTRAP; it should be set to the full path of a mysqld which does handle those options.

For example:

$ export MYSQLD_BOOTSTRAP
$ MYSQLD_BOOTSTRAP=/path/to/full/MySQL/bin/mysqld
$ mysql_install_db
$ make test
