libflashrom: Return progress state to the library user

Projects using libflashrom like fwupd expect the user to wait for the
operation to complete. To avoid the user thinking the process has
"hung" or "got stuck" report back the progress complete of the erase,
write and read operations.

Add a new --progress flag to the CLI to report progress of operations.

Include a test for the dummy spi25 device.

TEST=./test_build.sh; ./flashrom -p lspcon_i2c_spi:bus=7 -r /dev/null --progress
