Modifies the view tool to handle OFFLINE_FILE_TYPE_ARCH_REGDEPS traces,
leveraging the disassembly of DR_ISA_REGDEPS instructions.
When visualizing DR_ISA_REGDEPS instructions, the view tool still prints the
instruction length and PC, which for OFFLINE_FILE_TYPE_ARCH_REGDEPS
traces are the same as those in the original trace.
Then, after the PC, the instruction encoding, categories, operation size, and
registers are printed following the disassembly format of DR_ISA_REGDEPS
instructions (xref: #6799).

DR_ISA_REGDEPS instructions printed by the view tool look as follows:

[...] ifetch      10 byte(s) @ 0x00007f86ef03d107 00001931 04020204 load store [4byte]       %rv0 %rv2 %rv36 -> %rv0
[...]                                             00000026

We also fix a formatting bug in DR_ISA_REGDEPS instruction disassembly,
where we were missing a new line when the instruction encoding spills into
a second line.

Issue: #6662

when we encounter the filetype marker. We don't need
to set it for every disassembly of instructions.
(2 lines max, 8 bytes each divided in 4 byte words).
Using a single string for readability, even though we go over the
90 char limit.
