In some cases we don't have a particular address to read into so would
like one reserved. Adjust the read_file() method to support this.

We want to record the type of each file which is loaded. Add an new
parameter for this, to the read_file() method. Update all users.
Make bootmeth_common_read_file() store information about the image that
is read.

The current implementation is reading the whole partition for boot and
vendor_boot image which can be long following the size of the
partition or the time to read blocks (driver/SoC specific).
For example with mediatek mt8365 EVK board, we have a 64MiB boot
partition and the boot image flashed in this partition is only 42MiB.
It takes ~8-9 secs to read the boot partition.
Instead we can retrieved the boot image and vendor boot image size
with these new functions:
- android_image_get_bootimg_size
- android_image_get_vendor_bootimg_size
Use these information and read only the necessary.
By doing this with mt8365 EVK board, we read boot image in ~5 secs.
