Our infra should be capable to run all those deleted tests as now we've throttled the Fuchsia auto-rollers.

The current throttle is 1 PR / 3 hours for the 4 rollers:
- https://cs.corp.google.com/skia/buildbot/autoroll/config/fuchsia-mac-toolchain-flutter-engine.json?l=53
- https://cs.corp.google.com/skia/buildbot/autoroll/config/fuchsia-mac-sdk-flutter-engine.json?g=0&l=53

This is a subset of flutter#10485.
Hopefully this doesn't significantly reduce our coverage since we
have now limited the fuchsia auto-roller frequency.

We are severely resource constrained on the tryjobs. This is hindering progress on ToT due to scheduling failures and rate limits. There are no plans to requisition more resources in this infra scheme as the migration to tryjobs on LUCI is the preferred way forward. This patch removes presubmits that are somewhat redundant. Each removed presubmit and the justification is given below:

* `build_and_test_linux_opt_release`: The AOT variant is tested by `build_and_test_linux_opt_profile` (actually its replacement, see the next point).
* `build_and_test_linux_opt_profile`: When we build the host profile variant for Android, we test it as well instead of building the extra variant (since we already need a host for a target build).
* `build_and_test_android_unopt_debug`: `gen_javadoc` have been moved to the profile variant. `Roboelectric` tests have been moved to profile variant. JIT infra will be tested by the the host tests.
* ToT framework checks: These will be performed (by the autoroller)[https://autoroll.skia.org/r/flutter-engine-flutter-autoroll?tab=status] which also has a sheriff rotation. This will also avoid us having to ignore red presubmits on manual changes.

Everything else is left as-is. To be clear, this causes strictly less checks to be performed on each commit.
