[9.0](backport #4912) Convert Makefile to magefile.go

[mergify]

What is the problem this PR solves?

The Makefile has reached a point where it is becoming difficult to understand and add new features/targets.

How does this PR solve the problem?

Reimplement Makefile targets in mage.
Change buildkite pipeline to use mage.
Change Dockerfile* to use mage.

Added bonuses:

• Support for producing NOTICE-FIPS.txt
  • NOTICE files only contain modules used in shipped binaries.
• cloudE2E testing is functional
• Minor increase in parallel execution for targets.
• env only settings controls
  • target doc strings contain env var usage info
• conditional linter installation
• integration/e2e test token reuse
• improved release testing (archive structure, non-zero len binaries, fips capable indicators if FIPS=true)
• reimplemented bash scripts in dev-tools for mage, removed unused scripts.

How to test this PR locally

mage -l

See doc strings for targets with mage -h TARGET i.e.:

mage -h build:binary
Binary builds release binaries for the specified platforms. PLATFORMS may be used to set os/arch for compiled binaries. DEV creates a development build. SNAPSHOT creates a snapshot build. FIPS creates a FIPS capable binary. VERSION_QUALIFIER may be used to manually specify a version qualifer for the produced binary.

Usage:

	mage build:binary
