According to https://datatracker.ietf.org/doc/html/rfc7540#section-4.2

The size of a frame payload is limited by the maximum size that a
receiver advertises in the SETTINGS_MAX_FRAME_SIZE setting. This
setting can have any value between 2^14 (16,384) and 2^24-1
(16,777,215) octets, inclusive.

Our previous clamping to 0x3fff prevented us from writing more than
16K bytes at a time for HTTP/2.
See bug 1596576 comment 61 and bug 1596576 comment 54.

This patch doesn't change the default value of the pref, it just allows
us to experiment with a larger chunk size.

FWIW I tested my upload speed with the value set to 16k and 32k several times and didn't really see any consistent difference.
