[analyzer] Update the undefined assignment checker diagnostics to not use the term 'garbage' (#126596)
A clang user pointed out that messages for the static analyzer undefined
assignment checker use the term ‘garbage’, which might have a negative
connotation to some users. This change updates the messages to use the
term ‘uninitialized’. This is the usual reason why a value is undefined
in the static analyzer and describes the logical error that a programmer
should take action to fix.

Out-of-bounds reads can also produce undefined values in the static
analyzer. The right long-term design is to have to the array bounds
checker cover out-of-bounds reads, so we do not cover that case in the
updated messages. The recent improvements to the array bounds checker
make it a candidate to add to the core set of checkers.
