[GDB] MatchLog enum kind raises `TypeError` when printed

When debugging the MatchLog, it is desirable that every field be correctly printed without errors to the users/developers.

To reproduce this issue:

K Definition:

module TEST
  imports INT

  syntax Foo ::= foo(Int) | bar()
  rule [test]: foo(I) => bar() requires I ==Int 0
endmodule

kompile and krun:

kompile test.k --enable-llvm-debug && krun -cPGM='foo(1)' --debugger

On GDB:

(gdb) k start

...

(gdb)  python print(gdb.lookup_global_symbol('TEST.test.match').value()(gdb.parse_and_eval('subject')))
void

(gdb) python print(gdb.lookup_global_symbol("getMatchLog").value()()[0])
Python Exception <class 'TypeError'>: 'NoneType' object is not subscriptable

{kind = MatchLog::FUNCTION, function = 0x2f6560 <str_lit_side_condition_133> "side_condition_133", debugName = 0x2f6546 <str_lit_TEST.test.sc> "TEST.test.sc", result = 0x7ffff5500048, args = std::vector of length 1, capacity 1 = {0x7ffff5400088}, pattern = 0x0, subject = 0x0, sort = 0x0}

(gdb) python  print(gdb.lookup_global_symbol("getMatchLog").value()()[0]['kind'])
Python Exception <class 'TypeError'>: 'NoneType' object is not subscriptable
MatchLog::FUNCTION

Simple solutions: Work with Int or String
Harder solution: Workaround to pretty print the enum

Start with the MatchLog enum and the GDB Python access shown in the reproduction, especially the kind field returned by getMatchLog. Reproduce the NoneType exception with the provided K definition and debugger commands, then verify that printing the enum no longer raises a TypeError and that ['kind'] remains accessible.
