camel_to_upper() converts its argument from camel case to upper case
with '_' between words. Used for generated enumeration constant
prefixes.
When some of the words are spelled all caps, where exactly to insert
'_' is guesswork. camel_to_upper()'s guesses are bad enough in places
to make people override them with a 'prefix' in the schema.
Rewrite it to guess better:
1. Insert '_' after a non-upper case character followed by an upper
case character:
OneTwo -> ONE_TWO
One2Three -> ONE2_THREE
2. Insert '_' before the last upper case character followed by a
non-upper case character:
ACRONYMWord -> ACRONYM_Word
Except at the beginning (as in OneTwo above), or when there is
already one:
AbCd -> AB_CD
This changes the default enumeration constant prefix for a number of
enums. Generated enumeration constants change only where the default
is not overridden with 'prefix'.
The following enumerations without a 'prefix' change:
enum old camel_to_upper()
new camel_to_upper()

Add a 'prefix' so generated code doesn't change now. Subsequent
commits will remove most of them again. Two will remain:
MULTIFD_COMPRESSION, because migration code generally spells "multifd"
that way, and Q_KEY_CODE, because that one is baked into
subprojects/keycodemapdb/tools/keymap-gen.
The following enumerations with a 'prefix' change so that the prefix
is now superfluous:
enum old camel_to_upper()
new camel_to_upper() [equal to prefix]
