FESVR: Bump riscv-isa-sim to the latest to pick up DMACTIVE fix

See description(s) in

riscv-software-src/riscv-isa-sim#392

riscv-collab/riscv-openocd@906635c

This PR has massively increased in scope. In order to be able to bump spike annd OpenOCD, we also need to bump riscv-tests and GDB. It turns out GDB is now better maintained on FSF not riscv-binutils-gdb, so this PR is now attempting to install the FSF version instead.

Note this pulls in a bunch of other changes, I am not familiar if those will cause other issues.

They caused other issues :( I think we'll need to look at riscv-tests as well.

[mwachs5]

FYI @erikdanie... working to get a set of OpenOCD/GDB/riscv-tests that passes all tests.

[mwachs5]

@aswaterman , @jim-wilson I am not entirely sure the --disable-gdb argument is doing the right thing and the right FSF GDB is being used. I have this version of the tools installed locally... is there a way to check I am using the FSF GDB not the riscv-binutils-gdb?

[aswaterman]

@mwachs5 I confirmed that it's building the right one, and that --disable-gdb worked.

[mwachs5]

Thanks @timsifive . FSF 8.3.1 resolved the failing test. Hoping this passes all tests now.

[mwachs5]

@aswaterman does your approval still count against this much bigger PR?

[aswaterman]

Yes (thanks for checking :))

[erikdanie]

@mwachs5 Should I try running the fpgatests with this? If so, how do I pick it up?
