Catch integer overflows/underflows when parsing corrupt DWARF FORM blocks.

PR 22895
PR 22893
* dwarf2.c (read_n_bytes): Replace size parameter with dwarf_block
pointer.  Drop unused abfd parameter.  Check the size of the block
before initialising the data field.  Return the end pointer if the
size is invalid.
(read_attribute_value): Adjust invocations of read_n_bytes.
