anv/meta: Split anv_meta_blit.c into three files

The new organization is as follows:
* anv_meta_blit.c: Blit and state setup/teardown commands
* anv_meta_copy.c: Copy and update commands
* anv_meta_blit2d.c: 2D Blitter API commands

Also, change the formatting to contain most lines
within 80 columns.
