This moves the EE specific queries to EE modules that we prepend into
the background migrations. This requires some duplication of the SQL
queries, but there's sadly no way around this.

EE adds this method to Gitlab::Utils, which is also required by our
SimpleCov helper. This prevents us from injecting EE modules into
Gitlab::Utils, because the necessary bits for this are not yet in place.

To work around this we just backport try_megabytes_to_bytes, as there's
no particular reason to keep this in EE only.

This moves EE specific code out of Gitlab::UsageData and into
EE::Gitlab::UsageData. We also remove the overriding of the "CE" string
with "EE", because EE::Gitlab::UsageData already overrides this with its
own value.

This backports the allow_mirror_update update field for Chain::Command
from EE to CE. There's no particular reason to keep this in EE. Doing so
would require refactoring of CE as there currently is no easy way to
inject new Struct members into the Chain::Command class.

This ensures that we modify Gitlab::Regex using EE specific modules the
same way as we do with other modules/classes.

This moves all EE code out of Gitlab::PathRegex and into
EE::Gitlab::PathRegex.

This moves all EE specific code out of Gitlab::ObjectHierarchy and into
EE::Gitlab::ObjectHierarchy.

This ensures that Gitlab::HookData::IssueBuilder uses the same code in
CE and EE.

This moves EE specific code out of Gitlab::GitAccess and into
EE::Gitlab::GitAccess. This commit also removes a few redundant comments
that were not present in CE.

This moves the development favicon name in Gitlab::Favicon to a separate
method, allowing EE to redefine it to return a custom favicon.

This moves all EE specific code out of Gitlab::ExclusiveLease and into
EE::Gitlab::ExclusiveLease.

This moves EE specific code out of
Gitlab::Ci::Pipeline::Chain::Validate::Abilities and into
EE::Gitlab::Ci::Pipeline::Chain::Validate::Abilities. Since the moved
code was not tested in any way (that I could find at least), some tests
for this were also added.

This moves all EE specific code out of Gitlab::Access and into
EE::Gitlab::Access.
