fix(compiler): correctly parse attributes with a dot in the name (#32256)

Previously the compiler would ignore everything in the attribute
name after the first dot. For example
<div [attr.someAttr.attrSuffix]="var"></div>
is turned into <div someAttr="varValue"></div>.

This commit ensures that whole attribute name is captured.
Now <div [attr.someAttr.attrSuffix]="var"></div>
is turned into <div someAttr.attrSuffix="varValue"></div>
