[mojo] Rename .mojopkg to .mojoc

This commit begins the process of renaming `.mojopkg` files to `.mojoc`
files and referring to them as "precompiled files" where appropriate.
The precompiled files do in practice still contain a binary Mojo
package so some care must be taken, though in theory this change allows
us to precompile modules into the same format so a loosening of the
wording in certain places does make sense.

This follows the proposal on the forums [1].
