midx: rename get_midx_checksum() to midx_get_checksum_hash()

Browse Source 
Since 541204aabea (Documentation: document naming schema for structs and
their functions, 2024-07-30), we have adopted a naming convention for
functions that would prefer a name like, say, `midx_get_checksum()` over
`get_midx_checksum()`.

Adopt this convention throughout the midx.h API. Since this function
returns a raw (that is, non-hex encoded) hash, let's suffix the function
with "_hash()" to make this clear. As a side effect, this prepares us
for the subsequent change which will introduce a "_hex()" variant that
encodes the checksum itself.
