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


configure.in:
  WL#3670
  
  Add --disable-grant-options
mysql-test/install_test_db.sh:
  Add MYSQLD_BOOTSTRAP env variable, to enable test suite to work even if mysqld does not accept --bootstrap or --skip-grant-tables.
mysql-test/mysql-test-run.pl:
  Add MYSQLD_BOOTSTRAP env variable, to enable test suite to work even if mysqld does not accept --bootstrap or --skip-grant-tables.
mysql-test/mysql_test_run_new.c:
  Mention need for MYSQLD_BOOTSTRAP in a comment, in case this needs to be used with a mysqld which does not accept the --bootstrap option.
scripts/mysql_install_db.sh:
  Add MYSQLD_BOOTSTRAP env variable, to enable mysqld_install_db to work even if mysqld does not accept --bootstrap or --skip-grant-tables.
sql/CMakeLists.txt:
  Add DISABLE_GRANT_OPTIONS define
sql/mysqld.cc:
  Add DISABLE_GRANT_OPTIONS define, which removes the --bootstrap, --init-file, and --skip-grant-tables options
win/README:
  Document the DISABLE_GRANT_OPTIONS define
win/configure.js:
  Handle DISABLE_GRANT_OPTIONS
