[Security Solution] Implement prebuilt rule installation/_perform API endpoint

[banderror]

Epic: https://github.com/elastic/security-team/issues/1974 (internal)
Related to: #144060, #148181

Summary

Based on the API design made in #144060, implement the new rule installation/_perform API endpoint and hide it behind the feature flag.

POST /internal/detection_engine/prebuilt_rules/installation/_perform

Request body:

export interface PerformRuleInstallationRequestBody {
  mode: `ALL_RULES` | `SPECIFIC_RULES`;
  rules: RuleVersionSpecifier[]; // required if mode is `SPECIFIC_RULES`
}

export interface RuleVersionSpecifier {
  rule_id: RuleSignatureId;

  /**
   * This parameter is needed for handling race conditions with Optimistic Concurrency Control.
   * Two or more users can call installation/_review and installation/_perform endpoints concurrently.
   * Also, in general the time between these two calls can be anything.
   * The idea is to only allow the user to install a rule if the user has reviewed the exact version
   * of it that had been returned from the _review endpoint. If the version changed on the BE,
   * installation/_perform endpoint will return a version mismatch error for this rule.

Response body:

export interface PerformRuleInstallationResponseBody {
  summary: {
    total: number;

    skipped: number;
    failed: number;

    skipped: Array<{
      rule_id: RuleSignatureId;
      reason: 'RULE_INSTALLED';
    }>;
  };
  errors: AggregatedPrebuiltRuleError[];
}

interface AggregatedPrebuiltRuleError {
