Madhav Jivrajani 474031588a .*: sync go toolchain version and add ability to verify versions
This commit adds a script to sync the version present in .go-version
across all go.mod files as the toolchain directive. As part of that,
this commit also modifies go.mod files that did not have synced toolchain
directives.

Additionally, this also adds a script to verify all toolchain and go
directives against the version present in .go-version as follows:
(1) The go directive <= version in .go-version
(2) The toolchain directive == version in .go-version

This script runs as part of the `make verify` target, making it run
as a presbumit by default.

# This script looks at the version present in the .go-version file and treats
# that to be the value of the toolchain directive that go should use. It then
# updates the toolchain directives of all go.mod files to reflect this version.
#
# We do this to ensure that .go-version acts as the source of truth for go versions.
