ci: speed up CI by up to 50%

[smartcontracts]

Introduces a number of improvements to CI that significantly reduce overal CI time by up to 50% of the previous time.

Following improvements have been made:

• cannon-go-lint-and-test resource class changed to xlarge and parallelism is increased from 2 to 4, cutting down the time for this test from 10 minutes to about 4-5 minutes.
• pnpm-monorepo is removed entirely and replaced with contracts-bedrock-build and build-devnet-allocs.
• contracts-bedrock-build is run once with forge build and once with forge build --skip-tests so that any jobs that don't need to wait around for the tests to get built can get started 3-4 minutes earlier.
• install-contracts-dependencies is cached inside of contracts-bedrock-build.
• contracts-bedrock-tests is split over 4 parallel test runners to save ~2 minutes. We can save an additional few minutes if we properly record test timings for these tests. I will do this in a separate PR.
• golang-build-cache was being used incorrectly, jobs actually get their own build caches now and the caches are updated when necessary.
• cannon-prestate cache was broken because cannon and op-program were not being built, now it is actually cached properly.
• contracts-bedrock check for Solidity build warnings is moved into contracts-bedrock-build to save time and avoid compiling the whole codebase twice.
• snapshots-check gets a new added no-build option since we already built the contracts before it gets executed.

@smartcontracts did we mean to remove the validate spacers as its own job? If so, this is good to merge

Validate spacers just got renamed, whoops, the job was named incorrectly "validate-spaces"
