[gdb/symtab] Handle DW_FORM_strx in form_requires_reprocessing

Browse Source 
When running test-case gdb.dwarf2/fission-mix.exp using gcc-11, I run into:
...
(gdb) file fission-mix^M
Reading symbols from fission-mix...^M
src/gdb/dwarf2/attribute.h:258: internal-error: \
  void attribute::set_unsigned_reprocess(ULONGEST): \
  Assertion `form_requires_reprocessing ()' failed.^M
...

This happens when calling set_unsigned_reprocess on an attribute with form
DW_FORM_strx.  The assert triggers because DW_FORM_strx is not listed in
form_requires_reprocessing.

Fix this by adding DW_FORM_strx in form_requires_reprocessing.

Tested on x86_64-linux.
