Ensure the avalanchego binary is always current with a version-checked install

[maru-ava]

Previously the morpheusvm run script relied on manually building avalanchego from source. To ensure the required version of avalanchego is always used, a new script wrapping a version-checked install of avalanchego at the required version is introduced and the run script is updated to use it.

TODO

• Merge [tmpnet] Update rpc version check to tolerate usage of go run avalanchego#3869

Getting these warnings locally due to go run producing a message before the version:

Would you prefer the script doesn't produce that output, or that the rpc version ignore lines that aren't json?

Just noting it when I run. Ideally, a normal run does not produce a warn log imo

Before this PR is merged, ava-labs/avalanchego#3869 needs to merge and then this PR updated with a commit has merged to master.

[aaronbuchwald]

LGTM after merging #2022

[maru-ava]

Updated to install to a central location (~/.cache/versioned-binaries) so that worktrees (or other repos) can reuse an installed binary.
