MatrixRTC: Refactor | Introduce a new Encryption manager (used with experimental to device transport) (#4799)

Browse Source 
* refactor: New encryption manager BasicEncryptionManager for todevice

fixup: bad do not commit

* fix: ToDevice transport not setting the sent_ts

* test: BasicEncryptionManager add statistics tests

* code review

* feat: Encryption manager just reshare on new joiner

* refactor: Rename BasicEncryptionManger to RTCEncryptionManager

* fixup: RTC experimental todevice should use new encryption mgr

* fixup: use proper logger hierarchy

* fixup: RTC rollout first key asap even if no members to send to

* fixup: RTC add test for first key use

* fixup! emitting outbound key before anyone registered

* fix: quick patch for transport switch, need test

* test: RTC encryption manager, add test for transport switch

* post rebase fix

* Remove bad corepack commit

* review: cleaning, renaming

* review: cleaning and renaming

* stop using root logger in favor of a parent logger

* post merge fix broken test

* remove corepack again

* fix reverted changes after a merge

* review: Properly deprecate getEncryptionKeys

* review: rename ensureMediaKeyDistribution to ensureKeyDistribution

* review: use OutdatedKeyFilter instead of KeyBuffer
