into QR image (see also the "QrPixelsToQrImage2" metric).

The time to translate the sequence of input bytes into a vector of QR pixels

metric for that).
Recorded whenever `chrome/services/qrcode_generator` generates a QR code.
For example: when using the omnibox to share the URL via QR code, when using
WebAuthn, or when generating an RMA.
The metric is reported for only clients with high-resolution clocks (i.e.
excludes a small percentage of Windows users population). This is okay,
because we are mostly interested in comparing C++ vs Rust and it seems okay
to assume that such comparison would give similar results for the filtered
and non-filtered population.
