Add Support For New DW_FORM_data2 and other FORM tags in Juicer.

[lorenzo-gomez-windhover]

When writing location of members(DW_TAG_member) inside structs, sometimes the compiler may use DW_FORM_data2. As per the DWARF standard v4, Section 7.5.4 :

...

constant
There are six forms of constants. There are fixed length constant data forms for one, two,
four and eight byte values (respectively, DW_FORM_data1, DW_FORM_data2,
DW_FORM_data4, and DW_FORM_data8). There are also variable length constant data
forms encoded using LEB128 numbers (see below). Both signed (DW_FORM_sdata) and
unsigned (DW_FORM_udata) variable length constants are available

....

This issue DOES NOT include LEB128. Another issue by itself may make more sense for LEB128.

It might make the most sense to split up this issue, one per form.
