[EPIC] Phase out low priority symbolication

[loewenheim]

Since Symbolicator autoscales now, we hopefully shouldn't need the LPQ machinery anymore.

Things that remain to be done:

• https://github.com/getsentry/getsentry/pull/15531
• ref(lpq): Delete should_demote_symbolication #79965
• ref(lpq): Delete record_symbolication_duration #79976
• ref(lpq): Delete RealtimeMetrics code #80050
• ref(lpq): Delete LPQ from Symbolicator interface and symbolication tasks #80046
• https://github.com/getsentry/sentry-options-automator/pull/2575
• https://github.com/getsentry/getsentry/pull/15569
• https://github.com/getsentry/getsentry/pull/15601
• https://github.com/getsentry/getsentry/pull/15604
• https://github.com/getsentry/ops/pull/12668
• OPS Infra removal https://getsentry.atlassian.net/browse/INF-319
• https://github.com/getsentry/ops/pull/12748
• ref(lpq): Delete queues, options, killswitches #80310

The first step is #76788.

Increase JS Symbolicator max replicas to absorb LPQ traffic https://github.com/getsentry/ops/pull/11989

[loewenheim]

We're currently running on 80% of LPQ traffic going to normal Symbolicators. Before we switch it off entirely, we should increase Symbolicator autoscaling https://github.com/getsentry/ops/pull/12039.

[loewenheim]

No traffic has gone to the LPQ since https://github.com/getsentry/sentry-options-automator/pull/2324 and autoscaling is in a decent state.

Created a INF request to remove the LPQ Infrastructure: INF-319
