feat(windows): Add millisecond level precision when seeking

[SNNafi]

Description

This pull request addresses the issue related to audio seeking precision in the Audioplayers plugin for Windows. The problem is currently limited to seconds instead of milliseconds. The proposed changes modify the code to support seeking with millisecond precision, allowing users to accurately seek to specific points within an audio file.

Changes Made:

File: MediaEngineWrapper.cpp
Modified the SeekTo function:
Changed the parameter type from uint64_t to double for the timeStamp parameter.

Updated the calculation of timestampInSeconds to convert timeStamp from milliseconds to seconds (timeStamp / 1000.0).

Changed the call to m_mediaEngine->SetCurrentTime to use the updated timestampInSeconds value.

Modified the GetMediaTime function:
Removed the unnecessary assignment of currentTime in milliseconds.

Updated the calculation of currentTimeInSeconds to convert the current time from seconds to milliseconds (currentTimeInSeconds * 1000.0).

Return only currentTimeInHns instead of both currentTimeInHns and currentTime.

Modified the GetDuration1 function: Updated the calculation of durationInSecondsto convert the duration from seconds to milliseconds(durationInSeconds * 1000.0). Return duration`.

File: audio_player.cpp
Modified the OnTimeUpdate() method:
Updated the flutter::EncodableValue for the value field to directly use (int64_t)m_mediaEngineWrapper->GetMediaTime() instead of dividing by 10000.

Modified the OnDurationUpdate() method:
Updated the flutter::EncodableValue for the value field to directly use (int64_t)m_mediaEngineWrapper->GetDuration() instead of dividing by 10000.

Modified the SeekTo function in the AudioPlayer class to accept a double parameter instead of int64_t.

File: audio_player.h
Updated the function declaration of SeekTo in the AudioPlayer class to accept a double parameter instead of int64_t.

File: audioplayers_windows_plugin.cpp
Modified the seek method to use double for the position argument and directly pass it to player->SeekTo.

I would rather prefer to use double precision seconds everywhere. The conversion from milliseconds ms and hundredMilliSeconds Hns and seconds is quite confusing in my opinion. @SNNafi if you agree, I will push on top of it, with the improvements.

That sounds like a great improvement to code readability!

Thanks, @spydon for approving.
@Gustl22, Yes, please. It will be much better.

@Gustl22, It seems GitHub doesn't allow "Allow edits by maintainers" option, if PR is given from an org account. :(

@Gustl22 maybe we could just merge this to another branch than main and then you can continue with the remaining fixes on that branch?

Closing in favor of #1553, @SNNafi plz have a look, if it fulfills your needs ;D
