Subject: [PATCH] make_ext4fs: add option to specify the number of inodes

Add option to specify the number of inodes to create when
making the filesystem.  Read-only partitions don't have
a need for extra inodes, a lot of space is wasted by these
inodes.

Bug: 32246383
Test: make vendor partition with new options
